Keep On (10) Gry.{Shadwell Grylls} To let me have saving in cost of Bentley thick leaf rear spring. GRY{Shadwell Grylls} TO WRITE (11) Mths.{Reg Matthews} To issue report of progress so far with oil consumption. Ultimate object to be able to run on Castrol Z. (12) Swdl.{Len H.

Swindell} To complete tests on annealed Hall's bearings and issue a report. (15) Swdl.{Len H. Swindell} To complete endurance tests on stellited silchrome on lead fuel, valves run with close clearance. (16) Gry.{Shadwell Grylls} To issue a complete report for Sg.{Arthur F. Sidgreaves - MD} on the jack pads as running on B-56-BN.{W.O. Bentley / Mr Barrington} If we are no worse off than at present, say so. (17) Wym.{G. Harold Whyman - Experimental Manager} To complete detonation tests. (1) Water round back of head. (2) Salt cooled valves. | ||
