Inevitably, in preparing an enlarged Motor Show Number of Motor Sport last month for sale during the second week of the Earls Court Motor Show, we had to press on regardless, and a few errors crept in. The Lanchester Sprite, which we were unable to see on the Press-day, has a Hobbs automatic coupling and not a fluid flywheel as stated, while in an attempt to cover the valve-gear variants at the Show we omitted the Citroën 2 c.v. as an example of push-rod operation of inclined o.h. valves in a hemispherical head, made easy in this instance by the opposed cylinders. Our reference to plastic bodies at the bottom of page 674 should have been to Jensen, not to Lancia, and the correct type designation of the Alvis Graber saloon is TC108/G. Incidentally, although the B.M.W. 507 arrived on oversize Firestone Phoenix tyres, by opening-day the correct (6.00-16) Michelin tyres had been substituted, this then proving to be one of the best-looking cars exhibited.
Incidentally, further information now to hand shows that the increased power of the Triumph TR3 engine over that of the TR2 is achieved by using larger S.U. H6 carburetters, the compression ratio remaining the same, while, although the 120-b.h.p. four-cylinder Armstrong-Siddeley Sapphire 234 has a synchromesh gearbox with overdrive, the six-cylinder Sapphire 236 has, in addition, a Manumatic automatic clutch.
On the whole it was a good Show — 516,213 attended this year, compared with 523,586 last year, and supplies of Motor Sport were, like our staff on the stand, exhausted in two days.
