I have the same problem. I bought a ring off ebay that the seller said fit triumphs. Ended up that it obviously wasnt a speedmaster, maybe an older triumph model. Anyway the ring was too small, so i cut the sucker in half and took double sticky tape and put it over the scratched part. Lol. It looks pretty good but id still rather have a new ring, but like you guys said im not spending that kind of dough for one.
