Cox - Advertising Manager}Dly.DE. Bentley Jacks. Sg{Arthur F. Sidgreaves - MD}18/E21.1.36 I am in receipt of E.11/HP.20.1.36. I have been looking at a Bentley car and I agree that, if we try to jack a Bentley from the same points as a Rover, we shall run into difficulty because of the variation in the amount of lift. There is a good 3" difference on the Bentley between the back and front spring hangers but only about 1.5" on the Rover. It seems to me, however, that we can improve our scheme by the following: In the front of the Bentley have the lug on the front axle, either underneath it or preferably in front so as to be more readily accessible. At the back retain the present position, i.e. midway along the spring but have a lug on which the jack will hang as in the front, and I think it would be an advantage and reduce our difficulty of having a jack small enough to go under the spring when loaded if this lug were brought out to the side and slightly raised above the position of the present pad. If you are not clear in your mind as to exactly what I mean, I should be very pleased to show you on an actual car when I am at Derby. I am not at all keen on the scheme of jacking up from the running board because, in accordance with technical reasons given by Derby heretofore, we have been preaching against it for years owing to distortion of frame etc., and apart from this I am quite certain that anything that necessitated stiffening up our frame would mean a lot of testing, extra expense and delay, all of which I am anxious to avoid and which can be avoided by the introduction of the simple scheme I have outlined.
