This photo container is a Czechoslovak product used on the MiG-21F (in the documentation of machines that could carry this container after modifications of switches in the cabin, the manufacturer appeared "FR," which, as far as I know, was not used much). Several of these "twenty-one" were given test camouflage composed of "coke" black and dark green to better disguise them during reconnaissance flights against the ground.
But back to the photo container. It was equipped with four AFA-39 cameras, which captured the terrain vertically down, obliquely to the right and left down from the hanger axis and obliquely forwards down. The cameras were placed on a common carriage, which could be pulled out after unlocking the back cover of the container, so there was easy access to exchange films. Interestingly, the length of one film into the camera was 20 m. After hanging two containers, the entire target area was covered during the flight.
From the available documents, I could not find out that the container had any specific designation.
