I just got a 45x107 Kosmo Clack Stereo / Panoramic camera. It came with several holders, each good for one glass sheet. It also came with a Film Pack Adapter. I am certain of it's identity. I've never used a Film Pack, and can not find out how they were configured via google. I'm guessing there is not much to them other than paper & film. I guess 120 paper could be cut & taped to make a usable film pack. Can usable film packs be made from cut or roll film ( 120 in this case ) to make something for use in obsolete film packs in obsolete formats ? What is the configuration of the contents of a film pack ?
