This is a rare prewar FED telephoto lens, 100mm f:6.3. The lens is clean and smooth mechanically, the glass is also clean.
The lens was made in the late 1930's by the FED commune. It is exceptionally well finished and comes with metal rear and front caps. The case is made of cardboard covered by fabric.

At least 2 series were made - one with two pins (written 1st in the following list) and one without (written 2nd). Probably to help the owner to screw or unscrew the lens...
At least one lens shows a different design without meter scale ring (written 3rd)
