A.{Mr Adams} Robotham. Hs{Lord Ernest Hives - Chair}/Rm.{William Robotham - Chief Engineer}4/KT. Dear Sirs, We are in receipt of your letter of the 15th inst., and we would ask you to be so good as to advise us as to exactly the equipment you made the test on, that is the Car model, the year of make, mileage run if possible, and the method employed by you in ascertaining the efficiency, together with a diagram illustrating exactly the design of the parts included in the test, and how loads were applied and pressures indicated. On receipt of this we will then be able to advise you as to whether, in our opinion, the results might or might not conform to the conditions, because as you are doubtless aware, very varying results can be obtained by the introduction of mechanical parts under different conditions. With regard to the Lockheed system itself, the general overall efficiency is of course very high and remains so under normal working conditions. Awaiting further information from you, We are, Yours faithfully, AUTOMOTIVE PRODUCTS COMPANY P. Edward Boughton.
