| 1256 Rem/AJ.20/JH. 8th. May, 1940. The Manager, Light Production Co.Ltd., 60/66 Rochester Row, LONDON.S.W.1. Dear Sirs, I wish to know what material was used for the gudgeon pins on the Bentley V. {VIENNA} Their piece number was EB.2845 and were supplied by you just before the outbreak of war. If the steel has a B.E.S.A. and Air Ministry specification number, this will be sufficient. If not will you please supply us with its chemical properties ultimate tensile strength and brinell surface hardness. Yours faithfully, FOR ROLLS-ROYCE LTD. | ||
