| To Nor. Mto. From Hc. Ref:/HC.15.5.38 - H - R's memo. suggested a maximum weight of 33 cwt., and every effort will be made to keep down to this figure, but at the same time it has not been agreed that under no circumstances must it ever be exceeded. We have in many cases managed to get the 6-seater type of body down to this weight but we cannot always be successful and do not control a very large percentage of the bodies fitted to our chassis, a point which we believe is not appreciated by all concerned. It was further pointed out that we could not recommend the Board to approve of R's suggestion that bodies on RP's should be limited to 6-seater small bodies because statistics of sales show that if this move put into force, it would render the manufacture of the 20 RP chassis an uncommercial proposition. I should also like to make it quite clear that the items enumerated on page 4 of R's memo. are to be dealt with as follows:- (a). No bodies - Already dealt with. (b). Cancelling the "H" steering. This is not agreed. (c). No smaller wheels - this is already covered for "G" Series. (d). Central lubrication - do do do do do (e). Fit grouped instruments. This is agreed to on the material sanctioned after "G" Series. (f). Fit larger steering wheel with low controls. This can only refer to material beyond "G" Series, and our ability to act on this suggestion depends on the Design and Experimental Department. (g). With heavier bodies fit a lower geared axle. The remarks under (f) equally apply. (h). Highest practical engine revs., tappets not to jump cams until over dangerous crankshaft revs. The remarks as at (f) equally apply. It is hoped that this matter is now quite clear. Sg.{Arthur F. Sidgreaves - MD} | ||
