X.7530 X.5530 I am pleased you have arranged the instruments into the same space. I was Very anxious not to increase the depth - i.e. [Drawing of an instrument cluster with a line pointing to it from the text below] Thermometer is Slight error on blueprint marked ammeter, so I have altered my print. Mr. Minchin has that this matter is urgent. In our printed book of suggestions to buyers and coachbuilders we might give a position for the instrument board, to clear the knees of tall drivers, and be seen by the driver for each type of steering. Such a book if not already in existence should be compiled at once. If people stole the information it would still be better than not having it available, and would be an advertisement more valuable than not getting any advantage from it. Perhaps each specialist could contribute, but it would chiefly be DA{Bernard Day - Chassis Design}/EV{Ivan Evernden - coachwork}'s Dept. For instance weight distribution is the most important, and next the position of passengers - i.e. weight behind axle, passengers forward of ditto, give ideal positions, and how it improves riding, roadholding, and steering. I nearly forgot to mention that the starter press button should be available for the R.H. and not for the left for purposes which will be obvious: if not I will explain. R.{Sir Henry Royce} | ||
