Others have sold for several grand. I imagine it'd be like finding a NIB Colt SAA where the packaging had never been breached. Or a perfectly preserved barn-find Series IIa.
this is a long, long (long) time ago but...
In the early 80's my dad sold three Leica bodies, two turret mounts, around 20 lenses, cases, accessories and who knows what else. Mostly stuff from the 50's to 70's.
With that money, he bought three Canon cameras (one for me, him and my brother). Two lenses each, and cases. Plus a microwave for my mom, a mink stole and a solar hot water system for the house.
Crazy money in the 80's. I can just imagine what they would be worth today.
