Larry,

I believe these were roll stamped by machine, not gang stamped by hand. Remove the human element and the results look quite different.

I do not have any ghost numbers, but the 12Vneg is not as deep as the other markings. DSC02512.jpgDSC02511.jpg

Larry - in addition to the one on my car (above pic), I've got some other pics of '67 1100693 alternators that show variation in font, spacing and stamp depth, but no ghosts.

Michael: Maybe my eyes are deceiving me but is there not sometype of ghost or reflection to the right of the "A" in picture 1 and to the left of the "A" in picture 2?? Larry

Larry - hard to tell, but to me it looks more like a displacement of base material from the rolling action. It doesn't look like a double strike or bounce of the dies, which is what I believe is being referred to as a "ghost figure."

Patrick is dead on with his explanation of rolling the numbers on alternators. If you see any ghost figures it is because the one who "Stamped" them are in the restoring business of finding exactly the numbers you just happen to need.
As everyone can tell in the pics of the above alternators have all been restored.

...... I believe these were roll stamped by machine, not gang stamped by hand. ......

I thought the same (machine roll stamp)

Here's an unrestored 42 amp alt that I have. Early '64 T.I. (L76 w/o air, or L84). Obviously the machine hit the left side hard. Notice the small "v". This particular one must have been on one of the first batches of K66 Corvettes, as I believe the OK for the option was given late-December 1963.

There's a good chance this is the type of machinery used to roll stamp these parts. When I worked in a GM plant years ago we used this company for a number of marking applications.

George T. Schmidt Co. was the primary supplier of frame VIN stamping equipment, steel car VIN derivative body stamping equipment ("egg-stampers"), and gang holders and individual character dies in GM engine and assembly plants into the late 70's. They also supplied the "roll-stamping" systems for alternator case halves for the Delco-Remy alternator plant in Anderson, Indiana, which at the time was the most highly-automated plant in GM - copper wire and aluminum ingots in one end, 30,000 alternators out the other end every day.

Larry, Here's an odd stamping on an alternator, it's from a '74/'75 Monza/Nova, I think....Not a ghost but the XXX over the date code? I happened to come across this at an auction yesterday, of course I can't be certain when or who did this, but thought I'd share it.
