The first salvaged gun from the wreck of the 64-gun Third Rate HMS Anson (1781) on display. It has been laid on a Union Flag and a White Ensign draped over a table. Two White and a Blue Ensign are hanging behind the display. A framed display of photographs by the Gibson's shows the gun being raised on 14 April 1903. A watercolour print of the Anson being wrecked is resting against the gun in the centre.

The 'Lincolnshire Chronicle' reported on 17 April 1903 the raising of the first gun, stating that it came up with several cannon balls attached and a piece of gun carriage. The gun measured 10ft 6 inches in length and, including concretion, was estimated to weigh up to 2.5 tons.

The 64-gun Third Rate HMS Anson (1781) was wrecked in December 1807 and subsequently rediscovered by Captain H. E. Anderson, the chief officer of the West of England Salvage Company. A negotiated deal between him and the Admiralty allowed him to buy the wreck to undertake salvage work. The first items recovered were some of the guns, the first being on 14 April 1903.
