MAMIYA shutter size 0 Schneider Kreuznach ? Control Unit ?

To be true, we have NO idea what this is.

ATTENTION: Due to lack of power adapters, we can NOT check the set AT ALL, so could be partly defective !!! So sale as is, for repair or parts, so NO guarantee and NO returns !!!

2 things that look like electronic shutters size 0, with connecting cables. Shutters unengraved. In Schneider Kreuznach cases, that are lettered with "Mamiya Shutter" in German.

Matching a box that looks like kind of a control unit (with an antenna !!) with some kind of display.
Also the box is not engraved in any way with type or manufacturer.

From the inheriters of the first owner, we received among many other Schneider items also some very rare lenses, that are in the preproduction range, respectively were finally not produced in series.
So we consider it possible, that these items here are also Schneider preproduction items.
