Need help with Generator rebuilding parts assembly order...

[Zener424]

I purchased this generator with the intentions of rebuilding it and installing it in my '29 Town Sedan. I believe it is a B-10000, circa 1933, used by Ford to replace Model A generators in the later years. The rear end plate has ventilation holes. The front plate has been identified on the Ford Garage website http://www.fordgarage.com/pages/generatorchart.htm as 46-10139.
Here's my problem: The generator seems to have been previously disassembled, and I think it is missing some parts at the front drive end of the armature. I can't find an exact exploded view of this generator to tell me what parts are missing and the order in which they get installed. Can someone please post a diagram/photo that shows the parts required and the order of assembly? Thank you.
