Hey Everyone, I am trying to help a good friend identify this motorcycle he has. His father found it many years ago and can only remember that it was possibly a factory prototype Indian racer from the late 1920's or 1930's. There are no numbers stamped into the engine number pad on the left side of the engine but it does have 350 cast into the cylinder base. He believes the transmission is a 2 speed when he tries and selects the gears. If anyone has any information or photos of this bike from back in the day to help the owner figure out what the missing parts look like or at least figure out what model it is and when it was made would be a huge help.
