This is a work in progress.


The Mamiya Six II was introduced sometime in 1941 and initially sold for ¥384.[1] [2] Even though numbered Mamiya II, this is in fact the third model to have been introduced. Like the Mamiya Six Ia, this model has a red double exposure warning pane in the rangefinder window. The Mamiya Six II is essentially a Mamiya Six III design without the flash contacts. In common with the Mamiya Six III it also has the slightly smaller waist level viewfinder (10 x 10 mm) and a smooth rim to the central viewfinder window.

The production of Mamiya Six II models alongside the Mamiya Six III resumed in mid 1946 or early 1947. The price control list of 25 August 1947[3] includes the Mamiya Six II at a retail price of ¥8540[4] Less than a month later the price was set at ¥12220.[5]

Technical details

Like the Mamiya Six III from which this model is derived, the Mamiya Six II has the smaller waist level finder (10 x10 mm) and the dimpled shutter release button. The guide rail for the removable pressure plate runs for the length of the film gate and now exhibits an embossed directional arrow.
 
Distinguishing Pre-War and Post-War Production
Pre-war and wartime units can be readily recognised by the solid, cylindrical knob of the film advance, and by the use of three screws to fasten the flash-shoe. Post-war units have a mushroom-shaped knob of the film advance, and use two screws (set diagonally) to fasten the flash-shoe.

145 x 107 x 53mm (105mm open); 783g [6]

Mamiya Six IIa

As with the Mamiya Six Ia, this version of the Mamiya II allowed to use the larger (type '0', 58mm) shutters, which required to use a simplified two-part strut mechanism for the front door. This version was designed for photographers who wished to have faster (and thus usually larger diameter) shutters or have their own shutter and lens combinations installed.[9]
