Very early versions were prototypes, some fitted with Hexar 5cm f4.f lenses in Durax or Compur shutters. Some of these might date to before WWII. Among the regular production cameras, there are a number of variants. One of the very earliest examples (from March 1948[10]), the lens is a collapsible f/3.5 Hexar (four elements in three groups, with 26mm hood size), the shutter is a Konirapid (T, B, 1–500), the finish plate over the front of the shutter is black, with Konishiroku and concentric arcs picked out in silver, the distance scale is marked in metres, and the top also says Made in occupied Japan. Konishiroku is embossed in a large arc in the leatherette on the back, and, in some cases, MADE IN OCCUPIED JAPAN also embossed in the leatherette of the bottom plate. The price was ¥19,400. Approx. 4000 of the early black-face shutter versions were believed to have been made.
The next version (March 1948) with a shutter finish plate that is silver rather than black, takes a 32mm hood. Most were no longer marked Made in occupied Japan on top, only on the bottom. After approx. 20,000 copies, the large Konishiroku no longer was embossed on the back of the camera. Apparently some were made in error without MIOJ impressed in the bottom leatherette. Some examples have been found where a cutout was made and a small piece of leatherette imprinted with Made In Occupied Japan was inserted.
