Harley OEM 1936-64 Knucklehead, Flathead UL, Panhead manual advance and retard Big Twin distributor (circuit breaker) in excellent condition. Like many of the parts I'm finding in my storage unit, this part hasn't been on a bike in around 50 years. The holes in the drive gear and shaft are in great shape with no signs of egging. The bushings in the shaft housing are also in fine shape and there's no side play between the bushings and shaft. Any play in the drive gear mounting pin or shaft bushings introduces random error in the point gap setting and/or timing from what you set it to. The mounting plate on the housing is not bent up or marred in any way. No repairs have been done to this part and none are needed. Just add the correct size spacer between the housing and drive gear, the gear pin, and the circuit breaker base, etc. Basically, it's a like-new part with some cosmetic age spots. Check out the photos for more information. Ask questions before you buy, no returns. Additional photos available on request.
