Spec Notes

Fully manual: NO meter, NO battery, nothing electronic. Seiko #0 interlens leaf shutter with 5 blades, 1s-1/500. Coupled rangefinder. The 6x7 and 6x8 bodies differ from the 6x9 ONLY in the film gate - same body, same lens. 6x9 on 120/220. Lens is 5 elements in 5 groups per two sources, though one says 5 in 4. 67mm filter, minimum focus 1 m. FIRST GENERATION PARTICULARS: shutter has T but NO B, and the accessory shoe is COLD - the hot shoe arrives with generation II. 189 x 119 x 123 mm. FILTER THREAD DISPUTED on this generation only: 72mm per one source against 67mm everywhere else.
