The Hasselblad 500C/M was the third medium-format, single lens reflex camera (SLR) designed and produced in Sweden by Dr. Victor Hasselblad. Designed to capture 6cm x 6cm square images on 120 (12 exposures) or 220 (24 exposures) roll film, his first 2 cameras—the 1600 F (1948-1953) and 1000 F (1953-1957)—were similar in design, but featured focal-plane shutters, which proved to be finicky.
This Camera is a favorite of photographer Dan Rubin. See it in action below:

Part of the uniqueness of the Hasselblad 500-series camera is its modular design. The camera consists of a body fashioned from a single block of nickel-alloy, a lens, a film back, a folding viewfinder (or optional prism finder), and a film crank, each of which is interchangeable with almost every Hasselblad 500-series camera produced from 1957 through 2006, when the last Hasselblad 500-series camera was hand-assembled, in 2006.
