| 1280 8th March 1937. Rm {William Robotham - Chief Engineer} /Std.1/AP. Messrs John Marston & Co.Ltd., WOLVERHAMPTON. For the attention of Mr.Dunn. Dear Sirs, As promised in our discussion on Thursday last, we send you herewith drawings showing the mounting of the Bentley radiator, and the water connections for same and also drawings of the parts of our Phantom III. and Bentley radiator shells. It will be seen from the radiator mounting drawing that it is impossible to drop the bottom tank any further owing to the proximity of the front axle beam and brake levers in full bump position. From tests which we have carried out, we think that the minimum satisfactory frontal area of matrix using a 52.MM. Mk.Vl. {V. Lewis / Mr Valentine} block would be 420 square inches (our present area is 470 square inches). This figure could probably be reduced slightly by using a 58 MM. Mk.Vl. {V. Lewis / Mr Valentine} block. We hope that this will give you the necessary data to submit your modified design for our Bentley radiator. With regard to the Bentley and Phantom III. shells - we are today despatching to you a Bentley shell pressing as it comes off the press, before it has had any hand work - also a completed Phantom III. radiator shell. These are being sent on loan and we should like to receive them back in good condition after you have examined them etc. As promised during our discussion, you will submit quotations for the following - 1. Bentley shell - finished complete with bonnet rest angles EB.269/70 and EB.1639/40 and stiffeners EB.867 fitted. Note The bonnet rest angles can be in mild steel suitably plated instead of the present nickel silver. continued | ||
