Dave, you may be able to help Olivier with the history of his Colorado car....
I did some double checking and I think that the car was maybe built by Dan Robitaille. Dan rebuilt a LOT of Ts and really did a super job. One small bit of history if that is the car. He was on a Denver Model T Tour above Golden on road 40 on a steep hill. One of his buffalo wheels came off and rolled down the hill. The wheel rolled into a service station and knocked a gas pump over. Dan retrieved the wheel and I believe went home. I believe that Dan told me later that he took the buffalo wheels off and went back to wooden wheels. Of coarse he could have put them back on when he sold the car .I understand that he sold to someone in England. Dan is still alive but I understand is suffering from severe medical problems and is no longer active in the T club. I always thought that he did the best upholstery work on Ts that I ever saw.
