| To Hs{Lord Ernest Hives - Chair}/Rm.{William Robotham - Chief Engineer} Hs{Lord Ernest Hives - Chair}/FD.{Frank Dodd - Bodies}1/KW.10.1.35. Experimental Car 5-B-IV. We give below a summary of the chassis and body weights of the above Bentley Saloon. The coachwork on this car was not weighed before mounting. Both the chassis and coachwork are fitted with many non-standard features. We give below a list of the non-standard chassis parts and the corresponding increase or decrease in weight against standard. The idea is to arrive at the body weights, and the chassis features should be ignored for the moment, as they call for modifications and additions. Description of Part.
