And a VW search of "buffed reverse" revealed this page which shows a cool SSDC set of 26 varieties!
I added the Wow! references & links for the 83O's and 91O, but then noticed the '83O VAM-1C3 was missing. It's missing from the set on the SSDC too. Now, I know @andywoj00 has one awesome 1C3 example that he pulled from the bay a few months back, so there's at least one more out there. In fact his find is what gave me hope and started me searching again. (Still looking for the Broken Eagle, Andy)
From the Buffed Reverses VW page, it looks like more updates may be needed to the SSDC set. I don't know how to make those, but thought I'd mention it, in case others do. The buffed reverses are really cool, and some are probably easier to find than this 83O v1C1.
