Here I offer film back (cassette) for "Kiev-88 (TTL)" medium format cameras. Most likely, it will work with "Salut", but I did not check compatibility (as I do not have "Salut" now). 
Film back is loaded with 120 film with frame size 6x6 cm. Each film back will provide 12 frames.
There is an individual frame counter at the right side of the back. 

Film back has a removable metal plate - a dark slide, which protects the film from spoiling. Film back can be disconnected from the camera only when the dark slide is inserted, shutter of the camera can fire only when the dark slide is removed.

From the rear side there is a window covered with disc with film type. You must watch in this window when loading the film - you will watch the starting note which 120 film has.
