Hello everyone. A friend of mine submitted the following pictures for identification. All the markings are in German, the date is 1943 with 3 letter code manufacturer, the colour looks Luftwaffe, the construction also looks German, however, there no WaffenAmt Stamp whatsoever. Some have said it could be a lighting device for the aiming system "Flakvisier 35" or a filming device? Any idea or formal ID is more than welcome.
