Help with a German Stein

Hello Everyone,

I want to a small auction and found Three German Vintage stein.
The one shown below has the description of original award to Captain of Submarine U-505, the same one displayed at Chicago Science Museum.
Could anyone help me to identify if this piece is original or reproduction?

Thanks
Jing

 

The U 505 I belive refers to a wwII U boat.
U-505 is a German German Type IXC submarine built for Germany's Kriegsmarine during World War II. She was captured by the U.S. Navy on 4 June 1944.
In her uniquely unlucky career with the Kriegsmarine, she had the distinction of being the "most heavily damaged U-boat to successfully return to port" in World War II on her fourth patrol, and the only submarine in which a commanding officer took his own life in combat conditions on her tenth patrol, following six botched patrols. She was one of six U-boats that were captured by Allied forces during World War II, captured on 4 June 1944 by United States Navy Task Group 22.3 (TG 22.3). All but one of U-505's crew were rescued by the Navy task group. The submarine was towed to Bermuda in secret and her crew were interned at a US prisoner of war camp, where they were denied access to International Red Cross visits. The Navy classified the capture as top secret and prevented the Germans from discovering it. Her codebooks, Enigma machine, and other secret materials found on board helped the Allies to break Germany's top secret codes.
In 1954, U-505 was donated to the Museum of Science and Industry in Chicago, Illinois. She is now one of four German World War II U-boats that survive as museum ships, and just one of two Type IXCs still in existence with U-534.

 

Here is some info in a U boat captain named Axel-olaf lowe. The U boat history fits.

quite a find if it's authentic....

 

I can't find anything relating to steins given as awards. That said, I see no reason to doubt it's authenticity. dating the mark might be useful. I will give that a shot tomorrow.
A closer pic of the marks might be helpful.

 

I am not sure about this one, but one thing is that he did not sink ships of 50000, but only almost 38,000 GRT according to this page: https://uboat.net/men/commanders/745.html . Also there are way too many marks on the bottom, to me this looks as if the one who made this wanted it to look very authentic. Also the discrepancy between the perfect untouched condition of the inscriptions and the marks on the bottom and the worn off medals is a bit suspicious IMO. But I have to add that I am not at all familiar with such kind of items so I may be totally wrong.

 

complete BS, sorry. this stein is a new make, eventually sold in the Chicago museum shop. there were no beer steins as awards in the German forces. Axel-Olaf Loewe is described as being lackadaisical towards the regime in German sources.
