| X3498 To EFC. from ROY.{Sir Henry Royce} ROY{Sir Henry Royce}/M/28.6.30 Y4670 X3498 AMMETERS EFC1/AM/4.6.30 - There is no doubt in my mind that the Ferranti stands higher technically, commercially, and financially, than the Park Royal Company, and I have no hesitation, now we have practically decided to standardise a second source of supply for our Ammeters, in recommending Ferranti in place of Park Royal - Your tests, I understand, giving practically equal results, and the difference in cost being negligible. I gather you are circulating Standardisation Sheet for the Ferranti; and, should this be agreed by all concerned, I will make the necessary arrangements that the Park Royal Company be advised of our decision.
