| 3/ this it will improve the performance of the plug. So will you please state the minimum barrel length you can use. I am very glad to hear that the H.13 has come through its 10,000 mile test satisfactorily, & that you propose to standardise this model. Could you tell me if you intend to use it both on the Phantom & on the 25 H.P. Cars. I hope that we may get at last some of your orders for plugs on the 25 H.P. Car. I am very much obliged to you for testing the brakes on my car. I find them very good now & think the new linings on the front brakes have considerably improved matters. Please address your reply to me here where I shall be until the 29th inst. Sincerely Yours, Bernard Hopps. | ||
