    Hi There:
    Mike Smith of Antique Motorcycle Works in Oregon ought to be able to help you. I got a new crankpin from him a few years back, and he's constantly reproducing parts for Hedstroms.

    Interestingly, the '13 used a bronze bushing bigend, whereas 1914 and later used rollers. The board track racers all used the bushing setup past '13, which made me conclude that it was not such a bad system. Most Brit bikes of the period use bushings, and its simpler to fix.
