Here is my 2 cents worth. Picture below is mine and OK'd by Jerry MacNeish. I talked to John Pirkle (Now Deceased) on the stampings
of alternators and he indicated that a lot where slopy stamped. Many had that "ghost" figure we see all the time. Stamping of the alt.
where not in the same ballpark as engine stampings. (Where some where stamped on the slopy side also) I think most org. are trying to
make a science out of this from a time where no one cared how the stamp was including the stamper. IMHO Larry
