The 2 brush has a larger generator body, so there are different size front fork plates. The photo shows the larger 2 brush plate on the left, smaller 3 brush plate on the right. The other photos shows the bearings. On the bottom is the multi-part double roller bearing used 1932-1837, in the middle is the large 6303 bearing used in 1938-1939, at the top is the 6203 bearing used afterwards for non-fan mount pulley generators. There are many other variations. But this is a general overview.
Thank you. This is very helpful.
