Bill , I think I have a rear wheel for the bike in the first pic, sold to me as an Indian wheel, never been able to determine if it was or wasnt.!
There was a local shop downtown here, had scads of parts, lots of 45 and maybe other parts, frames, tanks, forks, etc... The owner was the motor officer here and rode a red Servicar.. he died in the 60,s in a traffic accident. His son later told me all the parts went to scrap or the dump..
.. I asked him why they did not keep them?? he said he was only 14 and his brother was 16 and did not care about that stuff.. He does however still have his dads 45 hillclimber..WR I think..(make Huge mental note to track down & beg him to sell, again)
