Hs. {Lord Ernest Hives - Chair} X11499 E {Mr Elliott - Chief Engineer} /JNR. {Charles L. Jenner} 3/HP.10.10.33. re Crankshafts. We send you herewith blueprint: LeC.3660 shewing two model half size crankshafts which are required for experimental use, to compare the four bearing shaft against the 7 bearings. These shafts are for a 6 cylinder engine, and although we are now more interested in 12 cylinder engines the comparative results of these two shafts will furnish the information required.
