| 319 c. Rm.{William Robotham - Chief Engineer} BY/Cgh.{W Clough}11/W.19.1.37. Phantom III : Four-Port Cylinder Head. With reference to RHC.{R. H. Coverley - Production Engineer}2/MJ.11.1.37, we have made enquiries and understand that the Experimental Department are not yet in a position to recommend the standardising of the four-port cylinder head at the present time. We are, however, having the detail drawings prepared in readiness with all the "operations" completed, so that they may be issued without any delay immediately a decision is arrived at.
