I think Russ, above is right...none were officially made in RHD but a few were converted to RHD by a company in Oxford back in the 50's. Gareth Roberts owns the ONLY one of these that is a convertible. A friend of mine, Steve Huckin used to own one of the coupe versions but he's now sold it and Buzz Burrell bought it and quickly sold it on to a friend of his i believe.
Do you own a RHD converted one?
