| -7- and reasonably as good as the Maconite. The surfaces however, of both Gloverite and Super Clover are rough as compared with Maconite 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 Clover H.T. cable in parallel with Maconite H.T. cable, provided Messrs. Glover can quote us a price comparable with that of the Maconite, and even if not, it might be worth while obtaining small supplies of Super Clover 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 Maconite 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. | ||
