263e E-unit part number

According to my copy of Olsen's CD, the prewar 263E uses a 260E-72 E unit (complete assembly).

Thank you! Using that I was able to search online and I found another forum that gave a cross-reference list for E-units. It looks like a 100-8, 100-11, or 2332M-10 will fit right in, the only difference being wire length.

The switch on the brush plate is used to turn the e unit on and off. The 763 e unit has no lever on it. If you use one of the 100 series e units I think you will be disappointed. The buzz like crazy and the 763 did not buzz.

Can you clarify? I’m not sure what you mean by the switch on the brush plate.

Excuse me.  I was talking 763 and you were talking 263.
