I’m watching an episode of treasure hunters that are looking for the remains of German U-Boats from World War II. They have found several articles, including a pewter knife handle and what appears to be a broken porcelain dinner plate with a partial logo on the bottom.
I did a quick Google search and found a couple of logos and then fed them both into Gemini. In this episode the divers have a video call with another expert and he verifies that it is a Luftwaffe (air) plate.



The logo on the right is almost spot on. The stylized eagle looks exactly the same, and the “U.V.” is on one shard of plate. There appears to be a “19” on one side of the logo, and “38” on the other. Probably the year 1938. This is what Gemini said about the image on the right:
The image shows a brown ink stamp or marking on a white surface. The central element is a stylized eagle clutching a swastika. To the left of the eagle are the letters “Fl.” and to the right are the letters “U.V.” Below the eagle and swastika is the year “1940”.
As identified previously, the “Fl. U.V.” stands for Flieger Unterkunft Verwaltung, which translates to Flight Barracks Administration of the German Luftwaffe during World War II.
The addition of the year “1940” indicates that the object bearing this stamp was likely property of or used by the Luftwaffe’s Flight Barracks Administration in the year 1940.
