Attention: Mr. W. A.{Mr Adams} Robotham Dear Sirs, We enclose herewith copy of a report of a test on the efficiency of the operation of the Lockheed Braking System, which has been made especially for you to compare with your own test, and this, we believe, should be comparative. You will notice the figures originally given for the efficiency of the Lockheed System are undoubtedly correct, and any loss obtained under other conditions can only be brought about by mechanical and other losses, which with proper care in design can be controlled within reasonable limits. Yours faithfully, AUTOMOTIVE PRODUCTS COMPANY. [Signature] E.B.Boughton Encl: Copy Test Report.
