DISTRIBUTOR X.800. Regarding the distributor, this appears to be distinctly defective, although simple to look at. There is a jump spark, and yet no ventilation, and the metal of the stationary pieces being brass, would not stand the nitric acid generated. There is no precaution taken in this distributor to prevent the backfire before mentioned. GENERAL. We are pleased to see, however, that the style of workmanship and manufacture is not of the cheap and nasty order so prevalent in American automobile construction. Regarding the cost, it would be hopeless for us to make the difference in the cost by altering the design between our coil and the whole of the Bosch equipment. It would be as well to lay these two out side-by-side, and ascertain the by difference in cost (if you like,/the criticisms of the Works Committee, but preferably by someone like Mr. Wormald) whether under equal manufacturing conditions, there should be such a discrepancy of cost between the complete Bosch electrical ignition system at £3.17.6 and our coil at 4.10.0. The experts would say whether it is a question of (1) Design. (2) Manufacturing conditions. (3) Accountancy. (4) Establishment charges, (5) or the rate of wages in England. As I have before remarked, it is absolutely necessary Contd | ||
