Film Pack Contessa Nettel Dekrullo Tropen discount

It is not 100% sure but this appears to be the film pack magazine for a Dekrullo Tropen 871 series camera. Film size appears to be 10x15cm. I hope the pictures will be helpful to determine which camera format is made for and the size of the film. An able engineer might transform it in order to accomodate cut film sheets.
The item is in good condition, only a few signs of tear and wear.

Mounts discount to camera with a 123mm Wide slider stepping down to 116mm for the main body with a length of 192mm excluding darkslide

Dark slide is good, body is solid and has no loose parts or joins. Latches, springs, etc... are all in good working order.

It is cleaned and serviced ready to be used.
