| TO WS. FROM EV.{Ivan Evernden - coachwork} COPY TO SG.{Arthur F. Sidgreaves - MD} SECRET. RE BONNET, RADIATOR & DASH. JAPAN III. I went to London yesterday to see the mock-up of the Japan III. bonnet, radiator and dash on a standard 20/25 HP. chassis. On examination it was found that the width of the bonnet at the back was approx. one inch too great. On our N.Sch.3208. we give the width of the bonnet over the side plates at the back as 36.ins. It would appear as though an error has been made by taking this dimension to be the width at the back of the dashboard. The bonnet overhangs the dashboard by 2.000ins. As this is a serious discrepancy we have had the mock-up taken down and Sales are returning it to you for correction. It was also found that the top tank of the radiator was approx. .275.ins. too high, which is somewhat serious in as much as there is only .375.ins. of rise on the side hinge. We suggest that you try this mock-up on a chassis in Derby before you send it to London again as we know how easy it is for these models to go wrong. I would add that, in spite of the fact that the back of the bonnet being an inch wider than intended, I thought that the appearance was very good, and much better than I8.G.4.
