Shooting the WERRA, camera from the DDR, with 13 year expired film - part 1

I was given a roll of 13 year expired agfa film (made in Germany) and decided to shoot it with what I consider one of the weirdest camera of my collection : the "Werra mat", made in east Germany (ex DDR) - the settings are bizarre and the look futuristic ; I never took the opportunity to use it before, so let's try it ! - part one is on the presentation of the camera, part 2 will show the photos.
