| -2- Harrison Radiator Corp. of course fully equipped for the building up of the hexagonal tube type of matrix, so that the equipment necessary appears to be that used for rolling out the copper strip. We assume of course that suitable copper strip can be purchased in this country. Yours faithfully, FOR ROLLS-ROYCE LIMITED. | ||
