RHC{R. H. Coverley - Production Engineer}! Hs{Lord Ernest Hives - Chair}/Ru.16/KW.11.7.34. Halford Silent Tappets. The Halford tappets which you have made us for the 20/25 have now reached the stage when we should like to put them on 21-G-IV and send them to France. You are making a filter to LeC.3959 for the Phantom silent tappets, we should be glad if you could put through a second one to this drawing for the Halford tappets on the 20/25.
