I just came across a little catalog I've had for sometime but hadn't had chance to read it. Its S&S Firearms 74-11 Myrtle Ave, Glendale, NY 11385, (718) 497-1100, www.ssfirearms.com. They have quite the selection of old and hard to find parts as well as a lot of really cool militaria,F.W.I.W.-SDH:D
