| - 2 - E.7/HP.16.6.33. We are reverting to the system of crankshaft lubrication which has done so well on the 20/25, so that in the end there will be no reason for high oil temperatures developing on J.3. We propose however to incorporate a Buick type ofcooler in the revised design. E.{Mr Elliott - Chief Engineer} | ||
