Mine is a 1953 Comet chassis with a 1950 twin engine, possibly someone thought of going from a single to a twin and just bought a 2nd hand engine. I bought a 1950 Comet 15 years ago with the intention of building a new twin engine for it but never got round to it as the one I now have came up at the right price.
Sold the Comet on.
