| EH. from R.{Sir Henry Royce} ORIGINAL. R5/W11.12.17. 3 X 3238 Re - Taper Bush for Valve Washers. We are sending you an improved design of taper cotter fixing for our valve washer. I consider this matter is urgent and shall be glad if you will test this improvement against the previous one and against the old screwed end, and find out which of the three is the safer. The last design calculates that the end of the valve is 30% stronger than the one made on Peugeot lines exactly. R.{Sir Henry Royce} [Stamp: RECEIVED 17 DEC 1917] | ||
