I had a guy come into my work yesterday talking about cameras and was admiring our antique cameras set-up. He was wanting answers to digital but I was wanting answers when he said he had a Leica C3. Is this camera worth anything? If it is, how much. Fun camera? Crap camera? He said somethin' about it needing to be oiled and stuff, I'm asuming it's just been sitting there. So, should I ask for it? And if so how much? Thanks!
