| X337 To RHC.{R. H. Coverley - Production Engineer} Hs{Lord Ernest Hives - Chair}/Gry.{Shadwell Grylls}10/KW.20.8.36. Propellor Shafts. We wish to revert to the use of Duckham's HBB grease for packing the sliding joint of all propellor shafts, and in particular that of 35-EX. We think the use of the thinner Mobilgrease No.2 has been the cause of our own joints running dry as well as those of several cars on production.
