| x7250 To BY.{R.W. Bailey - Chief Engineer} from ROY.{Sir Henry Royce} c. to WOF. c. to Hs.{Lord Ernest Hives - Chair} ROY{Sir Henry Royce}5/MG31.12.29 ------------------ The proposal to experiment with Radiators built up with square Tubes instead of our present standard Round will cost, as far as Tubes alone are concerned, approximately: £3. 0. 0d extra per PHANTOM II Radiator apart from the additional Labour charges involved in building up such square Tube Radiators with strip back and front. I understand from BY it is essential we should proceed with such experimental Radiators, and we are proceeding with purchase of the necessary Tube unless we hear to the contrary. It will take the makers 5-6 weeks to complete the necessary Tools and deliver Tubes. Will D.O please advise what strip will be required. ROY.{Sir Henry Royce} | ||
