So you are saying Tom, that any 1946 IIIc was also an "ex Army" and are now going for $1,000?! Then why did I have trouble almost giving away my 1946 IIIc? I took it to camera shows, put it on these forums, and barely got a bite at $250. I eventually had to sell it the other day on Craigslist for $150. It was very clean, had a mint case, had been CLA'd but wasn't perfect. I pulled the Elmar (when selling it that cheap) and put a Fed on it.
Know where I bought it? An antique store about 3 years ago. It was $500, with an Elmar 50mm and 90mm, and I told the store owner that was way too high. I offered $250 and he took it. So I was only out $100, plus $100 CLA, plus all my time!
I wouldn't touch another basic IIIc for $650, or even half that.
