| -2- We are confirming these figures, but in the meantime we shall be glad if you could ensure that the pistons which are being aluminited do not have a greater dimension 'I' than 3.247, and the bottom of the skirt dimension should not be more than 3.2475. With regard to the castings we are making for you, we have had to make a completely new die and hope to get some castings on Monday of next week. We should be glad if you could give us a quotation for machining 4 sets of pistons from these castings. Yours faithfully, FOR ROLLS-ROYCE LIMITED. | ||
