I just picked up a Hasselblad. It's a 500C/M, sports a split-image focusing screen, an eye-level prism, a 120 back, and a 150mm f/4 lens. Everything appears to be in excellent condition, and the only thing that's missing from the equation is a lens cap. The guy I bought it from was really cool, too, and delightful to talk to.
I just looked up the serial number. It was manufactured in 1975.
