| X5010 Ry. from E.{Mr Elliott - Chief Engineer} SECRET. A1/M27.5.29. Copy to Sg.{Arthur F. Sidgreaves - MD} HS.{Lord Ernest Hives - Chair} 20 HP. 'CHINA' CHASSIS. X5010. We send you herewith drawing Lec. 2703, shewing a design for an I section rod to suit a crankpin of 1.75" dia. No doubt you have already produced such a rod by piecing up the big end of the S.2 tubular design with a suitable stem but we should be glad if you would compare for detail differences especially in connection with the bolt heads and the radii where the stem joins the big end.
