A rollfilm holder (film back) fitted with a dark slide, designed as an adapter to use 120/620 rollfilm with 9x12 plate cameras, resulting in a 6x9 image (or smaller with a mask insert). Manufactured in the 1950s by the German manufacturer Rada.[1] A major competitor in the early days was the Rollex rollfilm back.
