| EFC4/ADS.12.29 contd. -7- and reasonably as good as the Maconit. The surfaces however, of both Gloverite and Super Glover are rough as compared with Maconit which makes them difficult to draw through the tubes and to fit ferrules etc." It would appear from the above that it might be worth while considering production supplies of the Super Glover H.T. cable in parallel with Maconit H.T. cable, provided Messrs. Glover can quote us a price comparable with that of the Maconit, and even if not, it might be worth while obtaining small supplies of Super Glover cable on production on the principle of "the second string". In general however, it may be said that we are using for present production as good a grade of H.T. wire as is perhaps at present obtainable. It should be pointed out that the above tests on chassis were made on a Phantom I chassis, and that circumstances on the Phantom II chassis are not, at present, so favourable to the durability of the H.T. wires on the magneto side. This set of wires is carried along in a tube underneath and in close proximity to the exhaust system, and it has been found in the case of standard Maconit H.T. wires which have been removed from Phantom II chassis for examination and test, that the condition of the wires referred to is not so good as those removed from a Phantom I chassis in the above tests. | ||
