Hey, that's my camera!
What I do with mine is load paper negatives in the darkroom, cut to about 4"x5" size, they sit on the film gate nicely, then you close up the double doors of the camera back.
I rate my grade 2 paper with an Exposure Index of 12; I'm able to use the lens settings on camera for the exposure, with reference from a handheld light meter, of course. Best of all, you get rangefinder focusing and a pretty good viewfinder.
I've also found that the camera can be reloaded out in the field using a large changing bag.
