Ekco - Round Five
Ekco released its first round radio, the AD65, in 1934. Four further circular designs followed, both the AD36 and the AD76 in 1935, the AD75 in 1940, and the A22 (pictured) in 1945. This was the last word in development of Wells Coates' original design, with the tuning dial turning a complete circuit, making the A22 the most elegant of the round Ekcos. It was the only one that included the shortwave band. The cursor is in the form of a light box that circles the dial, illuminating it from behind.
Two standard versions were available: walnut-toned Bakelite with a Florentine bronze ring, which cost £17.17s.3d; and more expensive black Bakelite with a chromed ring, as in this example. There are also known to be three genuine special order A22s, made of urea formaldehyde, two in red, and one (made for the 1946 Britain Can Make It exhibition) in marbled green. All other coloured A22s are fakes or copies.

Llandrindod Garages I - Automobile Palace
Commenced in 1906 and completed in 1911, what was originally known as The Palace of Sport, trading as Tom Norton Ltd from 1908, was founded by Tom Norton. Norton started in 1906 one of the earliest public bus services in Wales, between Llandrindod Wells and Newtown, held the first Wales-wide Ford agency, and was also a major agent for Austin and Ferguson.
The architect was Richard Wellings Thomas, and the building a very early example of steel construction. It was enlarged in 1919 to about three times its original size, providing nine bays along its curved frontage. Although built to the same Art Deco design, with faience facing throughout, the extension was constructed using reinforced concrete.
22 lions sejant-rampant, each with a shield, guard the building, which faces onto three streets. The elevation to Princes Avenue includes a pedimented entrance to No. 2 Garage. The ground floor fascia boasts faience tiles with raised lettering, including the word Aircraft. Circa 1913 Norton had invited pioneer aviator Gustav Hamel to give flying demonstrations from the nearby old race-course, in an effort to introduce aviation to mid-Wales.
The facility was renamed The Automobile Palace in 1925. It operated as a garage into the 1980s, and was Grade II* listed in 1985. Regrettably, much of the building is unoccupied, but it is home to the National Cycle Museum, a collection of over 250 bicycles that brilliantly charts their history. Apt given that Norton's first business was selling and repairing bicycles.

Llandrindod Garages II - Pritchard's
Also known as Central Garage, Pritchard's Garage was at one time a Rootes dealership, as evidenced by the aged signs for Commer, Hillman, Humber and Sunbeam. 11 lions sejant-rampant upon the parapet hold shields that give a completion date of 1929 for this fine concrete building, now largely unoccupied. The lions and the curved façade echo those of the nearby Automobile Palace.

UK Weapons of Mass Destruction
One of the normally inaccessible features of the Rhydymwyn Valley Works, developed by ICI in 1939 to manufacture and store mustard gas, is the tunnel system. Three tunnels (central one in bottom photo) were driven about 600 feet into the side of the valley, through limestone, and connected by four cross-tunnels, the stores (below). The system was designed to enable the storage of 3,120 tons of mustard gas, both Runcol and Pyro.
The site's production facilities were closed at the end of the war, when most of the UK's chemical weapons stocks were simply dumped at sea. But the country's then 'strategic reserve' of mustard gas remained stored in the Rhydymwyn tunnel facility until its destruction in 1958-60.
The store was ventilated by means of two huge extractor fans, at the top of the chimneys at the ends of each of the north and south tunnels. Air was drawn into the tunnels, deflected into a void above a mild steel ceiling throughout the storage areas, down through vents in this, and drawn out through grille-covered floor ducts, and up the chimneys. The steel ceiling was carried on concrete corbels.

Borderlands Rare Vintage Tin
The Clwyd Veteran and Vintage Machinery Show, held annually, throws up some real rarities amongst its shows of cars, commercial vehicles, bicycles and motorbikes, steam and stationary engines, tractors and horticultural machinery. The Lotus Europa (above) was a mid-engined GT, built in Hethel, Norfolk, between 1966 and 1975.
Karrier, part of Clayton and Co. of Huddersfield, started making small commercial vehicles in about 1907, and later moved into manufacturing buses and trolley-buses. It was bought by Commer, part of the Rootes Group, in 1934, itself acquired by Chrysler in 1967, who dropped the brand. This Karrier Bantam was a coal lorry.
NSU, an abbreviation of the company's home town of Neckarsulm, was founded in 1873. It was acquired by Volkswagen in 1969, and merged with Auto Union, who owned the Audi brand - the company name changed to Audi in 1985. The last NSU-badged car was the Ro80, with a twin-rotor Wankel engine and a semi-automatic vacuum transmission, built from 1967 to 1977.
Clan was formed in Washington, Co. Durham, in 1971, by a team of ex-Lotus engineers; and closed in 1973. It re-emerged as Clan Cars in the early 1980s, based in Newtownards, Northern Ireland. In 1985 it released the Clan Clover, with an Alfa Romeo powertrain. The company failed anew in 1987, having built only 26 Clovers.

Blackpool Tower - Highs and Lows
Blackpool Tower is Lancashire's answer to, and was inspired by, the Eiffel Tower. It was designed by Lancashire architects James Maxwell and Charles Tuke. Heenan and Froude of Worcester, structural engineers, both supplied and built the tower proper. Architects draw, engineers build.
Unlike its Parisian cousin, Blackpool Tower is not free-standing. Its base is surrounded by a monumental building that occupies 54,400 square feet, constructed from more than five million Accrington bricks. The tower proper is formed of 2,493 tons of steel and 93 tons of cast iron, hydraulically riveted together.
The foundation stone was laid in September 1891, and the tower opened in May 1894. 518 feet tall, the tower was inadequately painted during its early years. As a consequence between 1921 and 1924 all the steel-work had to be replaced.
The tower closed during WWII, and the crow's-nest was removed in 1940 to allow for the installation of a radar array, the station known as RAF Tower. Normal service resumed in 1946. The two hydraulic lifts were replaced in 1956-57 by electrically-driven ones. They were replaced again in 1991, and carry one up 315 feet.
A walk-on glass floor to the sea-facing side of the enclosed observation deck, over 380 feet up, was installed in 1998. Two open decks above this are accessible by means of stairways. Not accessible to the public are the 563 steps from the top of the brick building to the tower top, used by the maintenance teams, which coat the tower in nine tons of paint each time it's repainted.
Sadly, it is impossible to simply ascend the tower to appreciate the engineering. The only way up is to purchase an extortionately-priced 'experience', involving endless schmaltz and a pointless '4D' cinema show. These can both be bypassed if one insists, but the queues, disorganisation, bored staff pushing gift shop tat, and rip-off entry fee cannot. The tower is Grade I listed, and deserves much better.

Rochefort Transporter Bridge
Frenchman Ferdinand Arnodin, with Spaniard Alberto de Palacio, was the patentee holder for the first transporter bridge design brought to realisation, just outside of Bilbao, Spain. Five transporter bridges were built in France, more than in any other country: at Brest (relocated from Bizerta, Tunisia), Marseille, Nantes, Rochefort, and Rouen; with a sixth commenced at Bordeaux but never completed. All were designed by Arnodin. Only the Rochefort bridge remains to France.
Crossing the Charente River, construction of the 700 ton iron and steel Rochefort Transporter Bridge commenced in March 1898 and was completed in July 1900. The towers, marked with Arnodin's name on each of the 16 shoes, stand 217 feet high, and the bridge has an overall length of 575 feet, with a main span of 459 feet at beam level. The beam is 26 feet wide and 154 feet above high water level. The suspension cables terminate in massive anchorages (below). The uppermost cables run back to additional anchorages built in 1933 when the bridge was converted from being predominantly cable-stayed to being entirely of the suspension form.
The bridge was abandoned in February 1967 upon opening of a nearby vertical lift bridge, itself demolished in 1991 after opening of the Martrou viaduct road bridge (in background of first photo). Funds were put aside in 1975 for the bridge's demolition, but it was declared an historic monument in April 1976, and refurbished between 1990 and 1994.
The bridge is normally open in the summer months for use by pedestrians and cyclists. At the time of writing it has been closed for a predicted three year period, to replace the boom with one constructed much more closely in accord with Arnodin's original design, and to revert to the original largely cable-stayed format, at an estimated cost of £27 million. There is a good museum on the Échillais (Martrou) side of the river.

April Fools' Car Show 2016
The show winner was John Watson's immaculate 1910 Buick, complete with Selden patent licence plate. (Selden had never built a single example, but in 1895 was granted a US Patent for the automobile, much to the ire of Henry Ford.) Runner-up was Syd Brode's gorgeous 1950 3.5 litre Jaguar Mk V.

Bilbao - Ascensor de Begoña
In the heart of Bilbao's Casco Viejo, the Old Town, is a monumental and incongruous concrete structure that looks like it might be more at home overlooking a Soviet gulag.
It is in fact the Ascensor de Begoña, a set of elevators that takes one up to Park Etxebarri and the 16th-century basilica. The fare is €0.45 per trip, paid to the unfortunate elevator jockey who spends all day stuck in a lift.

Bilbao - Transporter Bridge
Puente Vizcaya, just outside Bilbao, and connecting Portugalete and Las Arenas, is the oldest transporter bridge in the world, the first of just 19 built to completion worldwide, and the only one built in Spain.
The bridge was designed by Spaniard Alberto de Palacio and engineered by Frenchman Ferdinand Arnodin. Construction commenced on 10 April 1890, and the bridge officially opened on 28 July 1893. The influence of the Eiffel Tower of 1889 is obvious.
Built of iron, it has a span of 525 feet, with towers 200 feet high and of 100 tons each, braced by cables that run parallel to the River Nervión. The original boom, gondola and traction gear weighed in at a further 400 tons. The bridge is joined together by 21,401 bolts and 10,629 rivets. The tower on the Las Arenas side housed a coal lift.
The truss was dynamited on 17 June 1937, during the Spanish Civil War, but service recommenced in June 1941, with a lighter boom and larger but lighter gondola. The bridge received in November 1998 its fifth gondola. This hangs from a 36-wheel trolley, is 82 feet long, and can carry six cars and 200 people at a time (bottom).
Still very much in use, operating every eight minutes during the day, every hour during the night, the journey taking just 90 seconds, the bridge is integrated into the ticketing for Bilbao's wider public transport system. Until 1999, except for a period 1941-45 when controlled from the gondola, it was operated from a booth up on the boom (above).
The 1998 overhaul included construction of ground-level waiting rooms and an enclosed walkway, with lifts at both ends, that enables one to walk across the river at about 147 feet above high water level (above). Known locally as the Puente Colgante, the Hanging Bridge, this world first was declared by UNESCO in July 2006 a World Heritage Site.

Echo of an Ekco
The cabinet of Ekco's AC-only AC77, designed by Serge Chermayeff, was available in both walnut Bakelite, and black Bakelite with a front panel and controls in ivory urea formaldehyde. Also available were AC/DC (AD77), battery (B67) and accumulator/vibrator (BV67) versions.
This working example of the black and ivory AC77 is doubly rare, in that it was manufactured, in 1936, at Ekco's short-lived Belgian factory, in Haren, near Brussels. Accordingly, the set uses French side-contact valves.
The Belgian operation was started in 1935 to counter the effect of continental import duties, levied by weight, but closed in 1937 for economic reasons. A sales and service function remained at Haren until the start of WWII. The back is branded differently from Southend-on-Sea-built Ekcos.

Rendsburg Transporter Bridge, Schleswig-Holstein
The Rendsburg High Bridge was the last of the three transporter bridges built in Germany: Osten opened in 1909 and remains in use, Kiel opened in 1910 but was demolished in 1923, and Rendsburg opened in 1913 and remains in use.
Designed by Friedrich Voss, construction began in 1911. The bridge was, and is, unique, in that it is properly a railway viaduct, carrying the Neumünster-Flensburg line over the Kiel Canal. From the central bridge (above) is slung a gondola such that the structure doubles as a transporter bridge.
Because the bridge carries a railway, a maximum incline of 1:150 was required. Accordingly, the whole structure is about 4.7 miles long, including the approach embankments. The trussed steel viaduct (first and last photos) boasts a total length of 8,156 feet, an incredible 1.5 miles.
The cantilevered central bridge is 966.5 feet long and has a main span of 459 feet. The towers are 164 feet high, and the bridge provides clearance above the canal water of 138 feet. A design quirk of the viaduct is that on the north side of the canal the 360-degree Rendsburg Loop carries the railway down to Rendsburg Station, at ground level.
The transporter bridge operates daily, making it one of just seven bridges worldwide still operating in transporter form. The journey between Osterrönfeld and Rendsburg takes just 90 seconds, and is repeated every quarter of an hour.
Regrettably, the gondola, which can carry four cars, but is largely used by pedestrians and cyclists, was in January 2016 struck by a cargo ship and badly damaged (above). At the time of writing, the transporter bridge was as a result not operating.
