Keith: Thankyou! I wasn't certain about the numbers of Crass models produced. I had my brother-in-law call Mid-South guns to see if they had a low-dollar version he could use for the parts he needs. We'll see how that goes. eBay is most likely the best hope for finding what he needs but, as you mention, you really need to know what you're buying before you close the deal. Patience and persistence should solve most of his problems if (big if) he knows exactly what he's looking at.
