Cowan's auction house in Cincinnati is selling off the lifetime collection of Richard Wray, a former President of Wray Electric Company and longtime collector of firearms.  This huge auction includes over 200 firearms and at least 90 rare class III  weapons.  

These guns are not display items, not deactivated or converted to semi-auto, they are the real deal.  Not only that, but most of these guns are rare as can be, and some are complete with all accessories.  This seems to be the auction of a lifetime. The auction is to be held April 30th, 2013.

Some of my favorites...
