| 20aa{D. Abbot-Anderson} HPS.{Horace Percy Smith - Experimental Factory Mgr} from Rm{William Robotham - Chief Engineer}/Gry.{Shadwell Grylls} c. to RHC.{R. H. Coverley - Production Engineer} Rm{William Robotham - Chief Engineer}/Gry{Shadwell Grylls}/7/R.23.11.36. Further to our instructions for 6-B.IV, will you please incorporate a propeller shaft damper of which the fly wheels are made in cast iron. We have been asked by production to cheapen the manufacture of this part, and wish to run in France cast iron fly wheels instead of case-hardened nickel steel.
