ID this alternator pulley

[Don_Lightfoot]

I purchased this about 10 years ago as a backup in case needed on my 69 Chevelle. It is in very good condition with the normal wear and tear around the hole. I am not knowledgeable enough to distinguish between original and repro on this item.

Looking for confirmation as to it being an original piece? Also, what are these things going for these days and what applications would it be for? I'm assuming it was at least used on all 837 alternators.

Once I know it is an original GM piece I will put it in the "for sale" section on here. Just want to make sure I am not misleading anybody.

Thanks in advance for any input.
