Wffm. MG34 Zwilling anti-aircraft spider sight
An extremely rare original Waffenmeister modified AA spider sight for the MG34.
Comprising an additional outer ring (to enable more accurate targeting of faster planes), this variation was most often utilised with the MG34 employed upon the Zwillingsockel dual MG mount.
This particular example is in used, as found condition with some surface corrosion throughout. The (un)locking mechanism to the base still lifts and remains fully functional.
Certainly one of the rarest of the rare when it comes to MG34 accessories!
