| To RHC. {R. H. Coverley - Production Engineer} +4698 Hs {Lord Ernest Hives - Chair} /Les.9/KW.19.7.34. Shock Damper Governor Units. In future we should like all governor units to have the main oil release hole drilled to Hs. {Lord Ernest Hives - Chair} 1465 instead of at the top of the spindle. This enables us to vent the top cover without losing oil from the unit. Hs {Lord Ernest Hives - Chair} /Les. | ||
