I am truly amazed that no-one seems to know this FAMOUS bike !!! It is the late Arthur Fogg’s machine and has been in many magazines and books, including “The First Scott Scene”. It was a TT Rep that was extensively modified at, of all places, the Panther works. So there is a LOT of Panther in there, including the wheels. I believe that Ken Swallow had a similar conversion done. Arthur kept it in immaculate condition, but I don’t know where it is now.
