B-56-BN.{W.O. Bentley / Mr Barrington} Replying to Sg.{Arthur F. Sidgreaves - MD}6/E.3.12.35. When Hancock refers to Commercial Petrol he means ordinary touring petrol such as No.1 Shell, as distinct from Ethyl or leaded petrols. We can change the head of B-56-BN{W.O. Bentley / Mr Barrington} when it comes back and let you try it. It ran its 10,000 miles test with the higher ratio. Hs{Lord Ernest Hives - Chair}/Rm.{William Robotham - Chief Engineer} | ||
