If it was gamer from the 80's, it'll have some or all of these:
1) Titan printed on the underside of the shaft, opposite of the Titan printed on the top of the shaft.
2) Date stamp, usually near the sticker at the bottom of the shaft or close to the heel.
3) Product code stamp, near the heel.
4) Very odd/big curve. Also could have abnormally long blade.
I have a TPM-1020 Fiberglass (Dave Reid) and it has #'s 1, 3 4 from the list.
From my experience, it isn't a pro stick or a gamer. Some stores did get name stamped sticks, that were never meant for pro players. The local shop I used to go to in Calgary used to get Flames players like Vernon, Neiuwendyk, MacInnis and the like.
