This led me to wonder what ever happened to the wreck.....
"The wreck was partially broken up in situ in 1942–1943, though parts of the ship were visible for some time after; the wreck lies at a depth of only 11 m (36 ft). The salvage rights were purchased from the German Government by the British, for £14,000, using a Montevideo engineering company as a front. The British had been surprised by the accuracy of the gunnery and expected to find a radar range finder, which they did. They used the knowledge thus acquired to try to develop countermeasures, under the leadership of Fred Hoyle at the British radar project. The Admiralty complained about the large sum paid for the salvage rights.
In February 2004, a salvage team began work raising the wreck of Admiral Graf Spee. The operation was in part being funded by the government of Uruguay, in part by the private sector as the wreck was a hazard to navigation. The first major section—a 27 metric tons (27 long tons; 30 short tons) gunnery rangefinding telemeter—was raised on 25 February. On 10 February 2006, the 2 m (6 ft 7 in), 400 kilograms (880 lb) eagle and swastika crest of Admiral Graf Spee was recovered from the stern of the ship; it was stored in a Uruguayan naval warehouse following German complaints about exhibiting "Nazi paraphernalia"."

A 150 mm naval gun salvaged from the German pocket battleship (cruiser) Admiral Graf Spee which participated in the naval Battle of the River Plate off of Montevideo and was scuttled in the River Plate on 17 December 1939 to avoid being sunk or captured by a superior British Royal Navy force. This gun is on display at the Museo Naval de Montevideo.
