Thanks to 52Carl I have a complete manifold but have'nt had the time or the weather to try another run. Got the numbers off of the generator today after scrubbing the plate with Scotchbrite and xylene. Best I can read with a light and magnifier is...
1102685 1G19.... or... 1102635 1G19
Hard to tell if it is an 8 or a 3.

I think it is 1940 vintage.
The starter is a 1107009 8L-9, which is from 1940.
