The Green Book shows the 68- part was replaced by the 81A- one. This is true for both pulley and generator. So, my question is: Did the original 68- generator have a different shaft diameter than the 81A- version? There is no part number on this part. Kube - is this in your area of expertise?

Not my area but I would hazard an opinion... I think this is '33 - '34. The cooling fins do not look correct for '35 - '36. Mike Driskell would know that.
The '39 pulley had an inside diameter of around .660" if I recall correctly. It is definitely not 39.
