| X.4046 Hs{Lord Ernest Hives - Chair}/Rml/LG. 3rd. Sept. 1925. Messrs. The D.N. Shock Absorber Co., 62, Oxford Street, London W.1. Dear Sirs, We should be interested to know if you could let us have a blue-print or sketch illustrating the constructions of your Shock Absorber. We believe that you supplied us with this information some time ago, but we are unable to locate it at the moment. We believe you claim your shock absorber to be superior to the Houdaille shock absorber. Perhaps you would point out where you consider you gain efficiency. Thanking you in anticipation. Yours faithfully, | ||
