I had a Miniature Sp Graphic that used cutfilmholders and I sold it for this reason. Later I bought a Linhof Rapid Rollex and this would slide in where cutfilm holders used to go and could evidently be used with most 2x3 cameras, including the Century Graphic and Technika, without taking off the ground glass. The drawbacks were it was 6x7 not 6x9 and also Linhof prices. Philip
