| J1280 Experimental Department Rm {William Robotham - Chief Engineer} /Std.10/AP. 19th December 1936. Messrs John Marston Ltd., WOLVERHAMPTON For the attention of Mr.Dunn. Dear Sirs, Referring to your letter of the 17th inst., for which we thank you. The writer will visit you on Wednesday next, arriving at approximately 11.a.m. if this is a convenient time. He is leaving his visit as late in the week as possible, in the hope that you will have received the sample American matrices and taken some test figures by that date. We are particularly anxious to discuss these various test results and get some idea of your future policy with regard to radiator cores. We wish to discuss the points mentioned in our last letter to you and in addition, the following ones. (1) Variation and guaranteed limits of matrix weights. This was referred to during the writer's last visit, but we have not heard from you on the subject. (2) Question of possibility of supply of Mk.VI. cores (lightened construction) for our Bentley & 25/30 cars until such time as a better core is available - we are anxious to obtain the advantages of the Mk.VI. core, if a considerable period will elapse before the new core adopted by yourselves is obtainable. (3) Proposed dimensions, particulars etc. of the car heater which you propose to manufacture - we are likely in the near future to be making definite provision for the fitting of heaters in our cars. We would mention that one of the factors which is likely to be of importance is degree of silence of the car heater fan and motor - of the heaters that we have tried, the Clayton is by far the most silent (presumably partly because of the small volume of air it handles etc.) continued | ||
