Gretsch was recently using the drop G badge again (briefly) before going back to the round badge last year. So there might be some newer snares out there with that re-issued badge...although they wouldn't be the same vintage as your other drums.
Gretsch was kind of on life support during the drop-G era so metal snares from that time frame may be pretty rare. I have a bunch of later 80's Burnt Orange drums and was always on the lookout for more, and Rosewood seems much easier to find, but you're right the stain colorations can vary by quite a bit.
