| RHC.{R. H. Coverley - Production Engineer} x237 Hs{Lord Ernest Hives - Chair}/Gry.{Shadwell Grylls}10/KW.1.6.34. PROPELLOR SHAFT DAMPERS. We should like to run on 4-B-IV a damper to N.Sch.3911, as this is the one we are likely to standardise. We have already instructed one for 21-G-IV and should like these two as soon as possible. There are various differences between this damper and the EX one such as a bronze bearing and bronze friction surfaces, which need trying out. Hs{Lord Ernest Hives - Chair}/Gry.{Shadwell Grylls} | ||
