| SG.{Arthur F. Sidgreaves - MD} FROM DA{Bernard Day - Chassis Design}/EV.{Ivan Evernden - coachwork} ORIGINAL Copy to HS.{Lord Ernest Hives - Chair} P. 2. REAR APRON. DA{Bernard Day - Chassis Design}/EV{Ivan Evernden - coachwork}1/M4.3.31. Y4531. We thank you for SG{Arthur F. Sidgreaves - MD}15/E3331. referring to BY5/G2331. It is true that we have had prints of Derby's layout of the above since the 30. Jan. Nothing has been done on account of instructions which I was given that J.{Mr Johnson W.M.} 3. took supreme precedence over P. 2. We regret that a considerable amount of work has to be done to make the proposed apron satisfactory in our mind. We would mention the following features: (1) The apron has been drawn to be suitable for the revised type 4. luggage grid used in conjunction with the petrol tank having a central vent. If you wish an apron for the present car a very different treatment will be necessary owing to the fact that there is a large and ugly K.S. gauge fitting and a vent to the filler. (2) The apron as drawn fits up against the back of the body and has to fit the curve of the back panel. The scheme was made not with a view to standardisation and manufacture by ourselves, but as an indication to the coachbuilders of a way of making an apron. If the apron has to be universal it will have to pass underneath the body, in which case it cannot rise up around the tank fittings except locally, which is not so good, and because it passes under the body it will be impossible to remove it without removing the body. This we think is not altogether desirable and would prefer that each apron be made to fit the rear panel of the body. One suggestion is that the coachbuilders might cut the apron off to suit.* (3) No toolbox is shewn in the space between the back of the tank and the rear cross member. We think that if we supply the apron we shall also have to supply the toolbox. This needs setting out. We therefore propose to make fresh suggestions to Derby as soon as possible, but at the moment we are striving hard to complete J.{Mr Johnson W.M.} 3. * If you agree to this suggestion the apron as drawn for P2. with central vent to DA{Bernard Day - Chassis Design}/EV.{Ivan Evernden - coachwork} is correct, but needs a toolbox.
