| Hs.{Lord Ernest Hives - Chair} from E.{Mr Elliott - Chief Engineer} c. to Sg.{Arthur F. Sidgreaves - MD} 47060 E1/M15.2.29. 'SS{S. Smith}' OIL PRESSURES. X.7010 X.7060 X.7000 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} | ||
