Mamiyaflex C The original C Professional was launched in 1956/7, and is very rare, with production rapidly swithched to the improved C2 (right). It is distinguished by having only one focus knob (usually on the right, although I believe some left-handed ones were made.

Mamiyaflex C2 The C2 was launched in 1958, improved mainly by two focus knobs rather than one, by a removable hood and the Seikosha-S shutter on the standard lens. Rack extension/ bellows focus down to 7" transformed the TLR market. SHutters were also improved.
