| To EFC. from R.{Sir Henry Royce} c. to BJ. X.3181 R3/W9.1.18. X.3181 - RE DALBY-WATSON & R.R. INDICATORS. X.2981 With reference to the Dalby-Watson and Rolls-Royce indicator, the scheme I suggested, if successful may avoid several of the troubles found with the Dalby-Watson indicator. It is so much simpler a scheme, not needing the very quick action. R.{Sir Henry Royce} | ||
