C. to - HS.{Lord Ernest Hives - Chair} BY.{R.W. Bailey - Chief Engineer} P. 2. - REAR APRON FOR USE WITH TYPE 4. REVISED LUGGAGE GRID. We are not clear on the policy decided on regarding rear aprons on P. 2. we agree that it is technically possible to supply a front apron on all chassis, but the same does not apply to the rear. Only 41% of the cars have no rear wheel at the back, so only 41% as a maximum require rear aprons. because of the varying lengths of bodies at the base and their varying shapes it is not possible for us to make an apron to match with the coachwork, and still be readily detachable. Derby have set out a rear apron on the lines of our sketch for the revised type 4. grid. it is made to suit an imaginary maximum body. We suggest that we should make one such apron and fit it to a car and photograph it. At the same time a drawing be got out shewing the construction we recommend. This information could then be given to the coachbuilders who will actually make the apron. This has two advantages: (1) We avoid giving the coachbuilder an apron for which he does not pay. (2) The apron can be fitted to the back of the body. DA{Bernard Day - Chassis Design}/EV.{Ivan Evernden - coachwork} | ||
