A.{Mr Adams} Robotham, Esq., Experimental Department, Rolls-Royce Ltd., Nightingale Road, DERBY. [Handwritten] Gry{Shadwell Grylls} Please deal with this Rm.{William Robotham - Chief Engineer} Dear Rm.{William Robotham - Chief Engineer}, I have just had a letter from Heron, and quote herewith a paragraph from it which concerns the recommendations he made to you for suitable valve material for the Bentley car:- "I have just been discussing Stelliting Bentley valves with Jardine and he says that they have found that they cannot satisfactorily Stellite the straight chromium steels I discussed with Rolls. Will you, therefore, please get six blue prints of the Bentley valve as soon as possible and Jardine will make up valves of a low expansion steel which can be Stellited and leaving the finish machining to be carried out by Rolls." This, I think, is self-explanatory, and if you will be good enough to send me the six blue prints he asks for, I will see that they are forwarded immediately. With kind regards, Yours sincerely, F.R.Banks. FRB/BB [Handwritten] Rm{William Robotham - Chief Engineer} Have written Jardine & Wilson Rich & ordered Valve forgings in latest Silchrome material also supply of No1 Haynes Stellite. meantime also enquired regarding supplies of this material in this Country WHC | ||
