A 17 lbs (7,7kg)bronze plaque depicting the official logo of the 1st U-boat flotilla. Very high relief and detail. Probably liberated from their headquarters after 1945. An important and unique piece of history!

Truly a handsome piece.
 

From Wikipedia
"The 1st U-boat flotilla (German 1. Unterseebootsflottille) also known as the Weddigen flotilla, was the first operational U-boat unit in Nazi Germany's Kriegsmarine (navy). Founded on September 27, 1935, under the command of Fregattenkapitän Karl Dönitz] it was named in honor of Kapitänleutnant Otto Weddigen. Weddigen, a U-boat commander during World War I, died on March 18, 1915, after his submarine U-29 was rammed by the British battleship HMS Dreadnought in the North Sea.

The flotilla at first only consisted of U-9, a Type IIB boat commissioned on August 21, 1935. Later, boats U-1 to U-12 were included in the flotilla, but U-1 to U-6 were only used as training boats and were attached to the U-boat training school in Neustadt. Originally based in Kiel from September 1935 – May 1941, it was moved to Brest, France in June 1941. In September 1944, the flotilla was disbanded and its remaining boats were distributed to other flotillas."
