| Hs.{Lord Ernest Hives - Chair} from DA{Bernard Day - Chassis Design}/EV.{Ivan Evernden - coachwork} c. to C. +4538 DA{Bernard Day - Chassis Design}/EV{Ivan Evernden - coachwork}3/M22. 8. 28. RE. 12-G4. COUPE. X.5830 X.4538 We understand from you to have said that the Barker Coupe Limousine (semi-flexible) weighs 32 cwts. for the complete car. Assuming a std. chassis weight and spares this gives a coachwork weight of 9 cwts. We are aware that Weymann bodies are not necessarily light, but we are surprised at this figure, for the Hooper 6-seater Sedanca, panelled, and with division, only reaches 9 cwts. We think that you should weigh the India chassis as soon as possible, so that we can see how much weight has been added by :- (1) The cross in the frame. (2) " 3" of extra wheelbase. (3) " new back end of the car. (4) " new engine feet. (5) " raised radiator. (6) " cast dash. We think you should then weigh the complete car carefully noting what accessories and spares are on board at the time, also the oil and water. Such a body as this, built on the lines of the sports car, could be produced at 5 cwts. at the most. We proposed doing this with the 3rd. body, the close coupled Coupe cabriolet.
