| Rm.{William Robotham - Chief Engineer}3/JMS. Ministry of Aircraft Production, Dept. T.A., Harrogate, Yorks. For the attention of Sir John Salmon. Dear Sirs, We understand that you have been making some enquiries as to the firing trials which took place on the 13.2 m/m Gun last weekend. These trials were of a preliminary character to prove the breech and barrel. We do not expect to have the gun firing as an automatic weapon for about a fortnight. Yours faithfully, | ||
