Hi Bob
You could try the bloke who was selling the Crayford converted one on Ebay, it obviously didn't get to near it's reserve, and is going to have some different mods. on it.
The same car was advertised in Rumcar news a few years back as well, and I know they said it was on the register.
Also Stuart Cyphus was involved with picking one up from France, if it ever got back to U.K. ??
Good luck
john
