In case anybody is wondering what the Cromard Special is/was, I found this description in The Racing Car Pocketbook by Denis Jenkinson:
“This was a one-off car developed from an early 6-cylinder twin-cam Amilcar by Bob Spikins and Basil de Mattos, of Laystall Engineering, the name Cromard was derived from the firm’s cylinder liner trade-mark. It was started in 1948 and each year, between racing, it was modified, first having a 1½ litre high-cam Lea-Francis engine replacing the Amilcar unit, and later a 1¾ litre Lea-Francis racing engine which developed 140 bhp. The chassis was improved by the addition of Volkswagen trailing link i.f.s. and swing axle rear suspemsion, while the Amilcar gearbox was replaced by a preselector E.N.V. Naturally it had a new body made for it. It was raced regularly until 1951, by which time it had served its useful life as a car for circuit racing.”
