A nice example of a WW2 Royal Navy cap, the Tally is for HMS Active, launched in 1929 and decommissioned in 1947.
HMS Active lived up to her name during WW2.
And 
At the beginning of the Second World War she joined the 13th Destroyer Flotilla based in Gibraltar and in June 1940 joined Force H. As such she took part in Operation Catapult against the French fleet in Mers El Kébir.[7] On 31 July Active set out from Gibraltar as part of Force H for Operation Hurry in which the aircraft carrier Ark Royal's aircraft attacked Cagliari in Italy as a diversion while the carrier Argus ferried 12 Hawker Hurricane fighter aircraft to Malta.[8] In August 1940, she returned to British waters, joining the 12th Destroyer Flotilla for operations in the Western Approaches and with the Home Fleet. From November 1940 to March 1941 Active was refitted at Liverpool.[7]
After completing this refit, Active joined the 3rd Destroyer Flotilla of the 
Home Fleet,[7] and in May 1941 the ship participated in the hunt for the German battleship Bismarck.[7][9]
In 1942 she participated in the Madagascar landings (Operation Ironclad) during which on 8 May she sank the Vichy French submarine Monge.
Later while being based in Cape Town on 8 October she sank the German submarine U-179 en route to Penang.
During the rest of the war the ship served as escort mainly between Great Britain and Sierra Leone after receiving increased anti-aircraft and anti-submarine armament. On 23 May 1943, she sank the Italian submarine Leonardo da Vinci with all hands lost west of Cape Finisterre together with the frigate HMS Ness and on 2 November 1943 sank U-340 close to Tangier.
In May 1947 Active was decommissioned and sold for scrap.
A good original cap from a ship that seen a lot of action during WW2.
