earlier generators were rebuilt with the wires in the later 30s so they would work on all the 4 cyl cars, would need closer pictures of all angles to determine each part though it looks like it is A generator with later wire, the original A terminal post could be installed
most of the later —33-34 type had aluminum end housings, rear one with vent holes, and one end of the field housing has a taper
take the brush cover off and take some pictures and it will show how much is “rebuilt”
