| EFC. from ROY.{Sir Henry Royce} X3860 ROY{Sir Henry Royce}1/MG214.26 Kindly advise if you are in a position yet to express any definite opinion as to the standardisation of "Maconite" High Tension Cable guaranteed within a diameter of 7 m/m minus .25 m/m, used for the High Tension Ignition Leads on the Chassis. I think the results of the exhaustive tests made by the Macintosh Company, which we saw at their Works recently, convinced us all that they had something exceptionally good here. As far as cost is concerned, the "Maconite" High Tension Cable comes out approximately 30/- per thousand yards over our present standard High Tension Cable. ROY{Sir Henry Royce} | ||
