X5830 DA{Bernard Day - Chassis Design}/EV{Ivan Evernden - coachwork}1/M20.3.26. 10-G-111 - NOW IN FRANCE. X.5840a. Xj5580 X.5380 X5800 K5500 Referring to Hs{Lord Ernest Hives - Chair}4/LG17.3.26., item 7. regarding the body subframe, the Barker patent cabriolet de ville is the heaviest type of 20 HP. body we sell, but is at the same time one of the most popular cabriolets. We do not agree with your remark that because the subframe weighs approx. 100 lbs. that this means necessarily increase in the weight of the coachwork by that amount, because it enables us to save weight in the body. We suggest that before we are able to state that the subframe materially increases the weight of the car, we should weigh 10-G-111, and also a similar car without the subframe. Regarding the floorboards, as far as the design goes there should be no difficulty in dealing with the front floor-boards. On previous subframe cars this complaint has been made and it has been found to be due to incorrect fitting. It should be realised that in no place must the boards fixed on the chassis contact with those on the body. This feature is often over-looked and the horizontal board is made to rest on both the chassis dash brackets and the subframe cross tube.
