To EFC. from R.{Sir Henry Royce} c. to CJ. Re - X.3290 - NOMOGRAMS. Thank you for the nomograms, we expect to find them quite useful. We are hoping, in reference to the "Condor" engine, to be able to run this at 1750, and to even get a slightly higher pressure than a mean pressure of 120, perhaps 125, in which case the HP will be perceptibly higher.
