| To BY.{R.W. Bailey - Chief Engineer} & Rm.{William Robotham - Chief Engineer} From RHC.{R. H. Coverley - Production Engineer} c. to Hs.{Lord Ernest Hives - Chair} 1310 RHC.{R. H. Coverley - Production Engineer}4/MJ.13.8.37. GRY{Shadwell Grylls}? SYNCHRO MESH CONES. With reference to the incorporating of a fine pitch groove on the Synchro Mesh cones, we find this has been adopted on the 25/30 HP. and Bentley Chassis and introduced into Production on the 31st. May 1937, and 31st. October, 1936 respectively, but has not yet taken effect on the Phantom lll. As the Phantom lll Chassis is considered to be the more important Chassis we should be pleased if investigations could be made immediately in order to ensure that this modification can be introduced with the least possible delay.
