I have a Meucci Original from 1980. It is a 2 prong....had a white/green spec wrap. I had the wrap changed to Black. The shaft reduced to 12mm. Anyway, I want to restore it back to the original issue and have a new 13mm shaft made to go along with it. The butt does have slight roll. Is it possible to True the butt up? I would post pics but can't do that now.
