Billy Record goes Panorama

I recently had the idea to load 135 film intp the Billy Record I (1951). That would produce a panorama with 24 x 90mm negative size, a dramatic 1:3.75 aspect ratio ! So I taped the small window on the back and put the 135 roll in between some tissue paper roughly in the middle. A first experimental test setup.

The result you see above. I am more than happy with quality, I just need to find a way to keep the film in the middle and the film forwarding needs some manual counting approach. After finetuning the whole process I will upload a more detailed instruction.
