HPS{Horace Percy Smith - Experimental Factory Mgr} [Strikethrough] E/JNR{Charles L. Jenner} .1/HP.22.4.37. Wraith III High Engine Mounting. We send you herewith:- LeC.5603 which is an alternative design to the previous one, and shows the torque rubbers spread to control at a large radius. We would prefer the mounting with the narrow centre rubbers because the scheme is cheaper. However, the experiments which are being conducted on Wraith II mounting will determine which scheme is the better. E/JNR.{Charles L. Jenner} | ||
