I bought these bikes today. The one with the white chainguard and "Ace" head badge dated 7/14/49 by serial# might be an Autocycle (B6?). I would probably restore it as such.The 12 hole rack has me stumped. The other bike dated 11/01/55 by serial# looks to be a Phantom missing rack,tank, fenders, wrong crank sprocket and wrong front wheel. Any thoughts on these would be appreciated.
