| - 2 - Continued:- We should also like the cost comparisons between the Mark III and Mark VI matrix blocks for the Ripple radiator, and the alternative forms of heater baffle which we requested you to obtain for us. We understand that you have made sketches of these baffles and we should very much like to have prints of them when they are completed. Yours faithfully, for ROLLS-ROYCE LIMITED. | ||
