A 2 inch aluminium sphere of the type used in the Teddington ship tanks during the development of the Golf Mine "bouncing bomb". Discovered in a box of Sir Barnes Wallis' lectures slides on the "Dam Busters" raid, the spheres were the next evolutionary step after the garden marbles leading eventually to the development of the Highball and Upkeep bombs.

Between 9 June and 10 September 1942, Wallis made use of one of the two large indoor water tanks of The National Physical Laboratory at Teddington on at least 18 occasions, he stated "I moored a wax model of a battleship several hundred feet up the tank, broadside on. We fired 2in diameter balls at it, when of course after hitting the freeboard of the ship, the sinking velocity of the ball combined with back-spin to move it towards the ship, and by adjusting the mean density of the ball we were able to pass it right underneath "the soft underbelly", to quote Winston Churchill.

Vickers Ltd -  A side view of the R80 Airship in Flight at Walney Island, Barrow in Furness, gelatin silver print photograph, published by Vickers circa 1920, 56cm x 70cm, within a stained wood frame 66cm x 80cm. Provenance: Sir Barnes Wallis thence by descent.  Note: The R.80 was a British rigid airship, first flown on 19 July 1920, and notable as the first fully streamlined airship constructed in Britain.  Designed by Barnes Wallis and H. B. Pratt for Vickers, it was originally commissioned as a military project for the British Admiralty but was ultimately completed for commercial passenger service. In practice, however, the R.80 proved too small to operate viably in this capacity.  After a brief period assisting in the training of personnel from the United States Navy who were to crew the ZR-2 airship, the R.80 was withdrawn from service and was eventually scrapped in 1925
