3A Autographic Kodak Special Model B
I bought this as an ornament then realised they can be adapted to take 120 roll film instead of the no longer made 122 film which made a negative 3.25: X 5.5" which meant postcards could be contact printed lots of old photos are postcards the example shows the size of the camera. When this model was first sold in 1916 it was 'Special' it's believed to be the first camera with a coupled rangefinder.
Autographic refers to a special film Kodak made which had an extra layer of tissue like paper, on the back of the camera is a flap which could be opened and using the metal stylus supplied you could write details of the shot on the border between the negatives expose it to the light and the information would appear on the negative.
Adapting it to take the much smaller film isn't to much of a problem you can buy adaptors for the smaller film then I need to make film guides and a pressure plate, the problem is the getting the bellows light tight it is possible to buy new ones very expensive so I need to repair them if you look on the internet there are all sorts of ideas non ideal, a local art shop suggested Acrylic paint mixed with a small amount of PVA glue, I bought a very cheap bellows camera and tried it worked and looks alright but tends to stick if I fold the camera so I'm thinking not to fold fold it make a case to carry it open. Unless any one has any ideas
