| BY. {R.W. Bailey - Chief Engineer} FROM DA. {Bernard Day - Chassis Design} C. to SG. {Arthur F. Sidgreaves - MD} HS. {Lord Ernest Hives - Chair} P.2. R.H. SIDE SPARE WHEEL CARRIER. Xy600 DAL/163. 7. 31. Herewith we send N.sch. 3303. shewing a layout of the proposed triangulation of the frame to stiffen the side spare wheel carrier on the lines recently sent you for 20/25. As we have no model car here we have not investigated every detail. As far as we can see the stays will go in as shewn out we should be glad if Derby would investigate the question more completely by means of a model. DA. {Bernard Day - Chassis Design} | ||
