| X7772 HS.{Lord Ernest Hives - Chair} from Da{Bernard Day - Chassis Design}/Ev.{Ivan Evernden - coachwork} C. By.{R.W. Bailey - Chief Engineer} OY. Da{Bernard Day - Chassis Design}/Ev{Ivan Evernden - coachwork}2/M14.5.30. X. 7260 X. 7772 X. 46131 P.2. L.H. BONNET. When sending you our N.sch. 3096. we said that we thought the bonnet could not project more than .075 beyond the back of the dashboard if we were retaining only our 3/8" isolation gap. At present we get 1/4" of fore and aft movement at the corners of the dashboard. When we use a continuous rubber strip in the place of the 4 rubber washers as we propose to do, in fact have to do, with the scheme intended, we agree that there will be no movement fore and aft relatively between the body and the dashboard. The latter will be carried with the body. We still think we shall get 1/4" of movement between the corner of the scuttle and the bonnet hinge. Since, however, we are anxious that this gap shall be reduced to a minimum, and that OY. tells us that 1/8" gap has been found sufficient on Springfield cars, we suggest that Hs.{Lord Ernest Hives - Chair} might mount the bonnet on the 2nd. L.H. P.2. - 25-EX - with only 1/8" gap, and experimentally increase this gap until the minimum permissible gap is obtained, when we should be informed so that the coachbuilders prints may record the final result.
