I have 1911 mags, most are "good" condition, 1930's Colt commercial production.
A bunch of L1A1 parts, nothing desirable like pistol grips or flashhiders, but a lot of the smaller parts..
A lot of old collectable ammunition, some in good packaging. Also, some "odd" stuff in standard calibers..(I/e US issue M-41 ball, odd european 7.63mm, and 9X19mm ammo in 25 round boxes.
I can see what this guy would be willing to chip in, as it's his computer..Says he has a bunch of old webgear, and assorted bags..
