| DA.{Bernard Day - Chassis Design} from Ha/Gry.{Shadwell Grylls} X129. Hs{Lord Ernest Hives - Chair}/Gry.{Shadwell Grylls}7/KT.16.2.33. PEREGRINE GEARBOX & TRANSMISSION. We are sending you a drawing showing the position of the oil level in the Peregrine gearbox on various up gradients. We think this should be useful in connection with N.sch.3687, as it appears that oil will tun into the extension and will not then be able to return.
