| X4308. PN.{Mr Northey} from EFC. c. Sg.{Arthur F. Sidgreaves - MD} Wor.{Arthur Wormald - General Works Manager} c. E.{Mr Elliott - Chief Engineer} Da.{Bernard Day - Chassis Design} c. Ey. H.{Arthur M. Hanbury - Head Complaints} EFC1/AD12.9.30. X.4308. A.T. SPEEDOMETERS. I have received your PN{Mr Northey}1/WT9.9.30. I am going into the matter more thoroughly and hope to be able to obtain information which will enable me personally to specify the necessary compression of the speed scale at the high speed end. For your information I attach a copy which schedules the information considered necessary to enable us to arrive at final recommendations for the standard instrument. EFC. | ||
