From the Rolls-Royce experimental archive: a quarter of a million communications from Rolls-Royce, 1906 to 1960's. Documents from the Sir Henry Royce Memorial Foundation (SHRMF).
From 'R.' to 'EFC.' posing several questions regarding electrical experiments, particularly comparing coils and contact points.

| X4275 To EFC. from R.{Sir Henry Royce} RL/M16.8.26. X.4275 X.2894 I should be very glad to know if you are sufficiently forward with your electrical experiments to come and see me any day after this week. The points are - Have you replied to Oy's memo. of June 11th. regarding the platinum points ? Have you a Delco and Bosch coil with nearly complete magnetic circuit in iron ? Are you satisfied that a comparison of the performance of platinum points and tungsten points shew sufficient advantage in the platinum points to justify their extra cost, and to make their use preferable to the inexpensively replaceable tungsten points ? Is there any difference between the American tungsten points and the English tungsten points ? How is it that our condenser, according to Oy. is less well insulated than the condenser of the Bosch Co.? How the Bosch Co. can work with such a poor earthing of their condenser ? Any many other questions too numerous to write. R.{Sir Henry Royce} | ||
