Martindale} c.c. to Da.{Bernard Day - Chassis Design} c.c. to HPS.{Horace Percy Smith - Experimental Factory Mgr} c.c. to RHC.{R. H. Coverley - Production Engineer} c.c. to WS./TB. 1015 7 Rm{William Robotham - Chief Engineer}/AFM.{Anthony F. Martindale}2/AP.7.7.37 WRAITH STUB AXLES. It will save cost and a good deal of trouble if the holes bored in the external ends of the Wraith stub axles are deleted and the ends cut off square, as part of the wireless earthing adaptors will then not be necessary. Da.{Bernard Day - Chassis Design} and WS./TB. have agreed that the holes need not be present, therefore will you please have the drawings altered before the dies are sunk, as a slight excess of metal will be necessary at the end of the axle. The working length of the earthing contact spring will be increased slightly. Rm{William Robotham - Chief Engineer}/AFM.{Anthony F. Martindale} | ||
