1929 Big Four bottom end - GONE

Tom sent these pictures of a 1929 Big Four (82x120) bottom end that he would like to swap against the 500cc version; preferably but not necessarily from the 1926-28 period. The crank turns freely and the two halves of the crankcase belong together. The only remarkable damage is to three of the four mounting lugs, but this can be fixed. Contact us for Tom's email address.
