| To-BY.{R.W. Bailey - Chief Engineer} from E/JNR.{Charles L. Jenner} E/JNR.{Charles L. Jenner}1/HP.7.3.33. x4533 CY.Mr. Hs.{Lord Ernest Hives - Chair} Bensport Series 1. -------------------- We send you herewith drawing: LeC.3397 showing the top water pipe, the Peregrine fan, and fan drive. This cancels the same parts shown on our previous drawing LeC.3289. It will be noticed that we have made the pulley on the end of the crankshaft smaller to keep down the peripheral speed of the belt, and the size of the pulley on the fan has been made larger to bring down the fan speed to .9 of the engine.
