I finally found the use of this optics, it is an auxiliary periscope sight for MG 30/42. I am very happy!!! MG Zieleinrichtung (MG Periscope Accessory), introduced
in late 1942. Using optical sights meant that the gunner had to position his
eye above the line of the mount, the result being he ran the risk – often
realized in the first years of the war – of being shot in the head by an enemy
sniper or counter-machine-gun fire. The periscope attachment meant that
the gunner could use the optical sight from a behind-cover position

To be more precise : it is not the Zieleinrichtung, but the “Vorsatzfernrohr”

A sort of binoculars which could be put on the Zieleinrichtung.
