| 1265 Da.{Bernard Day - Chassis Design} c. Rm{William Robotham - Chief Engineer} JNR.{Charles L. Jenner} E.2/HP.8.2.37. Oil Pumps. Rm.{William Robotham - Chief Engineer} tells me that he thinks we are still down on oil pump sizes both on the Bentley and the Phantom II, and this also applies to relief valve sizes. The case has been made worse of course by the use of arctic oil. Would you, therefore, please have, firstly a comparison made between the Bentley and the Phantom on the present basis to see how these proportion out relative to each other, and then consider an increase of 50% on the Phantom with a proportionate increase on the Bentley and 25/30.
