| X1371 To BY.{R.W. Bailey - Chief Engineer} from E/JNR.{Charles L. Jenner} c. Hs.{Lord Ernest Hives - Chair} Sft.{Mr Swift} RHC.{R. H. Coverley - Production Engineer} E/JNR.{Charles L. Jenner}1/HP.8.3.33. Peregrine Undersheets. We send you herewith: LeC.3392 - sheets 1, 2 and 3 showing the engine and the gearbox undersheets. In drawing these to the latest designs we have discovered that there are one or two points that require to be kept in mind - firstly - that the layout of the brake ropes on maximum bump are such that they are very close to the starter motor. Also that the new rear spring anchorage to N. Sch. 3622 appears to foul the front expansion box, RR/Sch.293. We suggest to get over this that the coil pipe to the front axle be moved to the offside of the chassis. As is usual with all new undershield designs, we think one set should be made up for trial and criticism. E/JNR.{Charles L. Jenner} [STAMP: RECEIVED 9 MAR 1933] | ||
