| - 4 - If you are interested in this device Mr. Stanton will assist in developing drawings and samples as required. Mr. Stanton stated that the real difficulty had been in developing reliable small poppet valves. In five years work he claims to have overcome this objection entirely, but gave no details. He promised to discuss this further if we were interested. Yours faithfully, ROLLS ROYCE OF AMERICA, INC. Maurice Olley | ||
