| 258 S/W. Rm.{William Robotham - Chief Engineer} We have now received the first official report of the weight of the "M" series Bentley as compared with that of the "L" series, and there appears to be an increase of ½ cwt. due to the overdrive gearbox, 6½" wheels and tyres and rear axle modifications. Would you please let us know whether you expected the increase in weight to be as much as this. Cx.{Major Len W. Cox - Advertising Manager} Kud | ||
