That is the #2 Folding Brownie. It uses 120 film. I have a #3A folding Brownie, looks just like that one on steroids. It uses 122 film, which is no longer made. I do have a few rolls of VP122 which were made in Kodak's last run in 1970. The negatives are huge, 3 1/2 x 5/1/2. The big challenge was to fabricate a reel so that I could process the film. I made one by modifying a Unicolor 120 reel. It seems to work ok. I will try and get some five inch Plus-X aerographic film to split and use in this camera. It has a really great B&L rectilinear lens. I paid $40 for mine. Found it on Fleabay.
