| To BA. from E.{Mr Elliott - Chief Engineer} Copy to CG. DH.{D. Henderson - Showroom} WH EPC. ORIGINAL E1/G13/6/19. x.3561. x.3531. RE 20 H.P. BONNET AND RADIATOR. We send you herewith drawing No. Lec.1104 showing the 20 H.P. Bonnet and Radiator quarter-scale, and a comparison between the appearance of the 40/50 H.P. and 20 H.P. cars to a scale of 1/20. The scuttle dashboard shewn is deeper than given on the coachbuilder's drawing of the 20 H.P. to enable the windscreen to be moved nearer to the front seats. It has been found necessary to add a small pocket to the right-hand side plate of the bonnet to accommodate the steering lever bosses. It may also be found necessary to slightly modify the magneto drive, so as to bring the magneto itself within the limits of the bonnet shewn. Particulars of this will be sent later. The radiator is supposed to be 4" thick on the outside, but the matrix is only about 2 1/2" deep, so as to leave room for shutters between the radiator and the fan. Would you please get a model of the bonnet made in wood, to the dimensions shewn on Lec.1104. Will you also kindly return us a filing blue print from the pencil drawing as soon as possible, and also three blue prints from Lec.1104 ink tracing, also as soon as possible.
