In reply to your TMH/VII/960/95 we note that you are experimenting with corrugations on the circumference of the sand drums. No doubt as a result of these experiments you will arrive at some definite particulars as to the number and shape of the corrugations, and the best dimensions. If you would then kindly send us a sketch giving these particulars, we will go into the question of producing them in quantities. Thanking you in anticipation. Yours faithfully, FOR ROLLS ROYCE, LIMITED. | ||
