Copies of an exchange of letters between Capt Geoffrey Duke Burton, Director General of Tanks and Transport, Ministry of Supply and Stern, in which Stern denied Burton's statement that the request of the Special Vehicle Development Committee, Ministry of Supply, of 11 Jul 1940, to borrow an A12 (Infantry Tank Mark II) for twenty four hours for testing at the works of William Foster and Company, Lincoln, Lincolnshire was in order to photograph the tank for use in a film, and Stern responded to Burton's criticism that film of a World War One tank previously shown by the Special Vehicle Development Committee, Ministry of Supply to the Tank Board had been misleading through being played at too high a speed. 1p
