We send you herewith LEC.3029 which shows two designs for an air valve. Scheme 2 follows the recent instructions from R.{Sir Henry Royce} We wish, however, for experiment one valve to be made to scheme 1. This is the same in principle, but has incorporated the central guide which we think desirable. [Stamp] RECEIVED 1932 MAR. 18 H E/JNR.{Charles L. Jenner} | ||
