Rare vintage item comes complete with glass plates x4 in total in a good condition for age see photos

These should work with any antique german camera that uses 4 1/2 x 6cm cut film. Just be sure you don't use it for more modern cameras like the Mamiya 645, or any other camera that uses specialized holders.

Could have been made for the Gaumont Block Notes camera, but I suspect they will work with most cameras of that type. Here is a useful link:
