MEMS [Handwritten]: 4302 [Handwritten]: GRY{Shadwell Grylls} Da.{Bernard Day - Chassis Design}1/MN.29.5.35. -------------------- SPECTRECodename for Phantom III REAR AXLE DIFFERENTIAL. As the differential of SpectreCodename for Phantom III I shews signs of being dry on the bearings and thrush washers, we have shewn on N.Sch.4509 suggestions for assisting the oil to reach these parts, based on what we understand was on the Ford axle, though we never saw this. We should like these slight modifications on the 10,000 miles car if possible. We also shew a modification to the differential box to prevent sediment being deposited on the outside of the wheel thrust washer, though we understand this cannot be put on the 10,000 miles car.
