There's a doctor in the Algiers area, that a HUGE WWII, WWI, and Civil war junky, with TONS of guns and memorabilia for sale soon. I've never seen his collection personally, but I've had many people tell me how impressed they were. Some of the higher end items are going up for auction, and someone dropped me off a catalog, but I left it at work.
Interested in any WWII, but I've been focusing on Allies and some neutrals (got a Swede and a Swiss) so far. Got a chance to visit the Springfield Armory Museum last summer and that was awe inspiring!
