I have been using Allparts for years to get the bone blanks for my repair shop. We switched from using white bone to the "vintage" bone because it was unbleached, did not smell absolutely atrocious when working with it, and even seems to lend a slightly smoother tone than the regular white. I am absolutely fed up with Allparts being constantly out of stock of the bone I want and would like to find a supplier that specializes in blanks of all sorts that you can buy in bulk and is not Stewmac.
I remember hearing of some place in Indiana a few years back, but my initial search has turned up nada. Anyone out there got some sweet reference?
