| X 121. To RY. from E/JNR.{Charles L. Jenner} c.c. Mr. Hs.{Lord Ernest Hives - Chair} E/JNR.{Charles L. Jenner}2/HP.4.2.33. re Peregrine Dynamo Drive. We send you herewith: LeC.3365 - showing the speed of the dynamo drive reduced from 1.5 to 1.2 times engine speed. This is a complete design and deals with the dynamo mounting, water pump drive, and pipes. It will be noticed that we have been able to simplify the machining on the crankcase of the dynamo cradle large facing - that is - we can now sweep the milling cutter off at the front end without any interruption.
