| Handwritten note (left margin): Re the copy we have. H.{Arthur M. Hanbury - Head Complaints} informed that all requested. TO HS.{Lord Ernest Hives - Chair} FROM EV.{Ivan Evernden - coachwork} COPY TO HS{Lord Ernest Hives - Chair} (Handwritten: Hy.{Tom Haldenby - Plant Engineer} 24-1-32) RE RADIATOR, BONNET AND DASH. J.3. EVI/17.12.31. Handwritten: X5250, X5260, X5500 We are about to set out the shape of the bonnet and radiator for J.3. and need some information from you by return. The top tank shape of the radiator will be the one now used and not the shallow one originally come for 18.G.4. The bonnet will have concealed hinges and be lengthened and widened very similar to the one already sent to you for the 25H.P. N.Sch.3381. On 20.G.4. which was here yesterday we noticed the rubber rest material. We shall wish to use this as originally done for J.3. last year, unless Hy.{Tom Haldenby - Plant Engineer} has made some further tests as he promised to do last Winter. If possible we would like you to post to us by the weekend a drawing of the latest cropped and shallower radiator, and also some drawing showing the positions of the hinges on the back of the radiator. It appeared that on 20.G.4. that the side hinge moulding had been raised to reduce the amount of top tank protruding above the top of the bonnet. We admired this and want to repeat it. On the first car we intending to use a standard radiator top tank and shutter mechanism but this will be followed by a scheme for a loose shell design having oval shutters. In this connection we would be glad to receive from you the shape of the section of the shutter which you can obtain economically, and also the latest information as to whether it is still thought desirable to go to the loose shell design, now that the Works have had a fairly long experience with stainless steel. | ||
