The Ford Barn

I have a couple of generators that I need to identify by date. Could some one please respond with the Ford dating code stamped into the field housing? Or a source for the information? I don't see it on Mac Vanpelt's site. I've lost my copy!!

Thanks!

I have not confirmed the later V8 stuff--yet, years ago when I was rebuilding generators for resale I didn't worry about this, and only noticed some dates on armatures

on model A generators I have confirmed by armature dates on original ones--

H-27 the month is the # 1-12, 1 jan, 2 feb etc
I-28
J-29
K-30
L=31
M-32 ---- the original A generators it is on the band, but later it is on the field
N-33 housing, usually with "FORD"
O-34 ---and continues

I think T is 39 and U is 40.

Generator codes.

1931=L 36=Q 41=V
32=M 37=R 42=W
33=N 38=S
34=O 39=T
35=P 40=U

1=Jan. to 12=Dec.
This only dates the body, so many have mixed matched parts!

Great!! Thanks!! Did the sequence continue during '43 and '44?. How about after the war - after "Z"? The units I have are in the 21A category.

The plot thickens. I have looked at three generators I have in my shop. One is configured for an 8BA style engine and is marked "Ford 9-1-1", one is in the 59A configuration and is marked "Ford 7-2-9". And the third is in the 59A style and the only mark I could find on the rusty case (other than Field and Gnd) is a "B". I'm guessing that's spurious and just there to confuse innocent people like me.

So, it appears that the system changed after the war. To what?
