I wanted to share a method to shoot 24x56mm panos on a Bronica SQ. It uses 120 film and gives you 23-24 pictures. I don't have the camera anymore and did it only once (with success). I made a thin mask to go on the film gate in front of the dark slide with a 24mm high opening. It was 3D-printed and lightly attached with double-sided tape. But you can probably just use some tape. Load the film and advance to frame one, and from then on toggle the multi-exposure switch. You can now cock the shutter with the crank, and advance the film with the knob on the film back. The trick is to advance it half a frame, approximately one half turn. The knob will properly stop at each full frame. You can test the correct advance with a backing paper roll and mark the frames with no lens on bulb.
Not perfect advance.

From what I understand you can do something similar on a Hasselblad but double exposure requires taking the back off.
