| -2- 6th. April, 1939. It will be essential for us to know the prices of the above on a production basis. The cost of the flexible pipe is especially interesting. We intend to mount the impulse coupling on the protruding shaft. Would it be possible to increase the length of this by ½" so as to give us more room? If so will you supply these pumps with the shaft end 2" from the joint face, instead of 1½" as shown. Yours faithfully, for ROLLS-ROYCE LTD. | ||
