| Rm.{William Robotham - Chief Engineer}3/JMS. 30.6.40. Major Bird, Messrs. Armstrong-Whitworth, NEWCASTLE. Dear Sir, I understand from Mr. Royce of our Glasgow branch that you may be able to undertake some gun boring and rifling for us. I shall be extremely interested to know what capacity is available, and whether the equipment would be suitable for dealing with a bore size as small as .5". Yours faithfully, | ||
