Hummel #055 (Modified for 18x24)

RCMP (Royal Canadian Mounted Police) model

The prism was factory-modified for viewing the half-frame format as was the film chamber. The winding mechanism was similarly modified so as to be able to count the 72 exposures that could be made with this camera. The camera is fitted with a 40mm f2.8 Heinz KIlfitt Makro-Kilar.
