| SECRET. ORIGINAL. To R.{Sir Henry Royce} From Hs.{Lord Ernest Hives - Chair} c. to Sg.{Arthur F. Sidgreaves - MD} Wor.{Arthur Wormald - General Works Manager} c. to W. Da.{Bernard Day - Chassis Design} c. to Ry. Hs.{Lord Ernest Hives - Chair}1/WJ.27.2.32. X5770. J.3 ENGINE UNIT. This engine unit has been on the bed again but we are not satisfied with the silence of the engine gears. We are therefore having another go at these. We think it is essential with this design of engine we must be able to build up engines with quiet engine gears, because it means completely dismantling the whole engine before we can do anything to them.
