837 Alternator Stamp Opinion
 

I know what I think but I also know there are much more knowledgeable folks about restamps than me.

Restamp or real?

The seven was probably a four.

No help here, but never seen that date before ? Anyone have Jan 69 dates ?

It’s fake IMO, You can see the file or sander marks where the 7 is.

- The area around the stamps shows marks and overall less casting grain than the surrounding area suggesting the surface has been worked.
- Although the numbers 7 and 3 appear double stamped / struck, other figures appear irregular including the 1, 0 and 9 which is suspect.
- The bottom alignment of the numbers appears uneven. Also suspect.

I would pass.

Offer him 10 bucks for it and smash it in front of him. Get it off the market.

Looks like a straight line below the numbers where the original numbers were milled off before restamping. If there is a straight line above the numbers caused by milling, that is positive proof it's a fake.
