I have seen all three types I mentioned with and without names. It all depends on the production run. As far as I could tell, they may well all three have been cast by the same foundry. They are all extremely similar in looks and quality. If you send those to Gary at Rocker Arms Unlimited, he can bush them and correct and geometry differences. Once he gets done with them, they will handle a .650 plus lift roller. Probably come close now, but for a reasonable amount they can be made virtually bulletproof.
