| GRY{Shadwell Grylls} +328 [Strikethrough: BT.{Capt. J. S. Burt - Engineer}] from HDY.{William Hardy} c. [Strikethrough: E.Hs.{Lord Ernest Hives - Chair}RHS.M--] HDY.{William Hardy}2/HP.25.9.35. Phantom 3 Gearbox. We send herewith N.Sch.4641 which shews an experimental rear crossmember for the gearbox made up from two of the existing crossmembers with a layer of fibre between to damp vibrations. The rear rubber mounting is as shown on the lower half of N.Sch.4463, which we understand is in stock. Bolt holes should be provided to suit the standard rubber as well, in order that the value of the crossmember alteration can be determined apart from the altered rubber. HDY.{William Hardy} | ||
