Hello, I have a difficult question and I hope that even if I will not be able to get an answer someone here can help me a little with forming a clearer idea about it. I have an album of photographs from a relative from the years 1935-36. The photographs were taken in Africa, but the camera used for them was bought in Italy. The camera itself is lost. The prints are sized (in cm) 4x5.5, 5x5, 4x6, 5.5x8, with the smallest sized photos being contact prints. I have a very blurry detail in one photo of the person who took the pictures wearing what I assume is the camera case, which looks like the case of a folding camera, but as I'm no expert I am not sure if the case can be of any use to identify the camera. I am including the detail so that you can see it. I know this is very little information, but any clues about which model may have taken the pictures based on age of the photographs, prints size and on camera case will be more than welcome, thanks!
