From left to right in this image are the Model 1, Model 2 and Baby Brownie cameras. They are all made of bakelite, and all take 127 film. This film is no longer available but instructions exist [YouTube] that explain how to cut down 35mm film to suit- and of course 35mm film is still able to be processed today.
Model 1 has lost its winding mechanism, but comes in its original carry case. It has a Meniscus f/14 lens. Model 2 has a larger, Dakon f/11 lens. The Baby Brownie has a Meniscus lens and a flip up viewfinder. It has a button under the lens for brief time exposure, and it too has its own original carry case.
The three cameras are for sale: $AUD125
