| 1280. March 28th.1938 Rm{William Robotham - Chief Engineer}/Std.10/AP. Messrs Elo-Birkbys Limited, Liversedge, YORKS: For the attention of Mr.Whitehead. Dear Sirs, We regret that there is still a point on our drawing EW.1665 (filler cap plug) which is not quite clear, namely, the recess at the top of the internal hexagon - your interpretation is unfortunately not correct. This is intended to be as shown on drawing i.e. with a spigot of 1.650 dia. .100 deep at top of hexagon and no chamfer or bevel except the .050 radius shown. We have marked up your sketch (attached) to indicate this point. Yours faithfully, FOR ROLLS-ROYCE LIMITED. | ||
