You are correct, the eight proofs auctioned off my Mastro in 1999 were not from the mid 1970's "proof" find.
The T3 proofs from the find still pop up here and there in the different auctions. The T206 Mathewson white cap from the find was auctioned off a year or so ago. Outside of the unissued Collins, I believe that this was the best T206 in the find.
