| 1258 Rm{William Robotham - Chief Engineer}2/R.{Sir Henry Royce} 13th April, 1939. J.{Mr Johnson W.M.} Howlett, Esq., Wellworthy Piston Rings Ltd., LYMINGTON, Hants: Dear Howlett, [Signature] Many thanks for your letter of the 12th April. I am not an expert on Patent wording myself, and, apparently, from what Blackith says, we have not done very well on our 'Provisional'. Under the circumstances, I will come over and meet Mr. Hardman Brown on Tuesday next, the 18th instant, at 11.0.a.m. I never thought that we should be able to get a patent on this piston to cover Diesel engines, and, of course, we have no idea whether it would do the slightest good on a Diesel. Yours sincerely, | ||
