Yashica 6×6 TLR (crank advance)

The Yashica company made a long line of 6×6 TLR cameras, comprising many models which were the result of a gradual evolution rather than radical change; they are conveniently divided into knob advance models and the crank-advance models discussed here. These were branded Yashica Mat to reflect their automatic film advance, unlike simpler camera using a red window.
