1129 To HPS.{Horace Percy Smith - Experimental Factory Mgr} c. to HPS{Horace Percy Smith - Experimental Factory Mgr}/WSC.{W. S. Cassel} Rm{William Robotham - Chief Engineer}/Ed.{J. L. Edwards}9/JH.22.2.39. WORK INSTRUCTED IN SHOP. Single Cylinder Unit. (1) Replacement valve seat in No.4 head, instructed Rm{William Robotham - Chief Engineer}/Ed.{J. L. Edwards}7/JH.20.2.39. This job is urgently required and should be given maximum priority. (2) Two new cylinder heads instructed By/Ald.{F. Allwood - Experimental Design}16/G.5.10.38. These heads are urgently required, and whilst we appreciate the pressure of other work, we consider four and a half months too long for the manufacture of two single cylinder heads. We should be glad therefore if you would have these heads completed by the end of this month. (3) Extensions pieces for Farnborough indicator valve instructed Rm{William Robotham - Chief Engineer}/Ed.{J. L. Edwards}8/JH.20.2.39. These are only small pieces, and we should like to have them ready for use by Monday next. (4) Farnborough indicator valves, instructed on same memo. as (3) may be treated as of slightly less priority, though we should like to have them by 1.4.39. (5) Modifications to valve gear instructed By/Ald.{F. Allwood - Experimental Design}2/AW.15.2.39. This should be urged as rapidly as possible, since the engine can be handed over for modification as soon as the parts are sufficiently far advanced to warrant shutting the unit down. B.60. (1) Cooled and solid exhaust valves instructed in By/Ald.{F. Allwood - Experimental Design}1/AW.30.1.39. This should be complete as soon as possible, as seats have been ordered and are to hand. (2) Modifications to B.60 head instructed By/Ald.{F. Allwood - Experimental Design}1/AW.13.1.39. should be urged, as the future B.60 head design depends on test results obtained on these modified heads. Rm{William Robotham - Chief Engineer}/Ed.{J. L.
