| ORIGINAL HS.{Lord Ernest Hives - Chair} FROM E.{Mr Elliott - Chief Engineer} SECRET. E1/M15.2.29. Copy to SG.{Arthur F. Sidgreaves - MD} SS.{S. Smith} OIL PRESSURES. x7010 x7060 x7000 We should be glad if you would let us know at some convenient time to what figures the various oil pressures, high, intermediate, and low, attain when starting from cold on the SS.{S. Smith} We think the intermediate should reach quite a useful pressure during the warming up period for forcing the cold oil to the various parts of the valve gear. E.{Mr Elliott - Chief Engineer} | ||
