So I just got a Zeiss Ikon Ideal 225 Folding Camera and it works great, but it did not come with a film holder. I tried doing some research online, but there is hardly any information. I looked on ebay for a film pack meant for this type of camera and came up empty. Is there any other film holder that can snap onto the back like I am supposed to use for my camera or any alternative? I found on ebay a listing for ICA 3x4 1/2 film plate holders and I know my camera used to be ICA so I am wondering if that would work. Any information would be happily received since I know very little of the camera. Thanks!
