Yup, it was me with the CIB.
I bought it off Ebay in a lot with a toploader and 5 CIB games. No idea what I had until years after I sold it to a member on NA who live overseas. I contacted him several times after that, but he isn't interested in selling it back.
Then, randomly I found a bin for a 3 screw cart only and bought it. Made the post on NA about it, then put it on NA auctions, where NES Gangsta bought it....for $250 I think.
I have seen one other 3 screw Stinger cart on Ebay in a large lot games, but it was in the sold listings. So, there are more out there.
