I've had a few really great finds. One of the best was a Leica M2 (1960) near mint with a case full of lenses. In all there were 8 Leica M lenses, 1 Zeiss Sonnar 1.5 (early coated but damaged glass). 2 visoflexes, bellows, ton of adapters, filters, 2 ball heads and a mini Leitz tripod. also in the deal was a like new (absolute mint new) condition with 50mm summicron IIIG. All for just under $1500.
The second best find was a like new 4x5 baby Deardorff with 210mm Zeiss Tessar in an Ilex shutter, case and five new Graflex wooden holders in the original wrapping. I don't think the camera had been used as there was no evidence any holder had ever been inserted in the back. Got this package for $800.
Both came from little antique stores.
