ARK ROYAL WW2 Shipwreck Treasure 1941, Museum Item, Sailor Silver? MUG Original.

Description

HMS Ark Royal (pennant number 91) was an aircraft carrier of the Royal Navy that served during the Second World War.
Desire n'a pas Repos – "Zeal Does Not Rest"
Designed in 1934 to fit the restrictions of the Washington Naval Treaty, Ark Royal was built by Cammell Laird and Company Ltd. at Birkenhead, England, and completed in November 1938. Her design differed from previous aircraft carriers. Ark Royal was the first ship on which the hangars and flight deck were an integral part of the hull, instead of an add-on or part of the superstructure. Designed to carry a large number of aircraft, she had two hangar deck levels. She served during a period that first saw the extensive use of naval air power; several carrier tactics were developed and refined aboard Ark Royal.
Ark Royal served in some of the most active naval theatres of the Second World War. She was involved in the first aerial and U-boat kills of the war, operations off Norway, the search for the German battleship Bismarck, and the Malta Convoys. Ark Royal survived several near misses and gained a reputation as a 'lucky ship'. She was torpedoed on 13 November 1941 by German submarine U-81 and sank the following day; one of her 1,488 crew members was killed. Her sinking was the subject of several inquiries; investigators were keen to know how the carrier was lost, in spite of efforts to save the ship and tow her to the naval base at Gibraltar. They found that several design flaws contributed to the loss, which were rectified in new British carriers.
The wreck was discovered in December 2002 by an American underwater survey company using sonar mounted on an autonomous underwater vehicle, under contract from the BBC for the filming of a documentary about the ship,[2] at a depth of about 1000 metres and approximately 30 nautical miles (35 mi; 56 km) from Gibraltar.
On the mug said ARK ROYAL and DESIRE N'A PAS REPOS.

I'm not sure that the mug is a silver or silverplate? And probably been saved before the ship wrecked or maybe after? but have a really nice patina look in to it from that period of time.
