I have been going back to the pictures by ewu and kodaker. It finally occurred to me that they are coloured versions of the Vest Pocket Kodak Model B which was manufactured from 1924 to 1935.
There were numerous minor variations of the camera. See the number of folds in the bellows of the pictured cameras for example.
I have 9 of them. Each differs from all the others in one or more ways. It could be; the location of the tripod socket, the colouration of the viewfinder, the variations of its frame pattern, the focusing rail lock, the film advance key design, the leatherette pattern, the various lenses, their place of manufacture, etc. They make an inexpensive but fascinating collection sideline.
Every one was still operational when I got it, not even a leaky bellows. That says a lot for Kodak quality and durability.

Hi Colin, some other readers asked me this question too. I took a instax mini film out from the case and put it into the camera. After exposure, I put the film into a empty film case and used my instax mini to develop it.
I will write another article to talk in detail how to do it. Now I m using this method to test my old cameras.
