| 1021 Rm.{William Robotham - Chief Engineer}17/ML. 19th. April, 1940. Breedon, Esq., Messrs. Wilmot Breeden Ltd., Eastern Works, Camden Street, BIRMINGHAM.1. Dear Breedon, Thank you for your letter of the 16th. April, together with the information about the various oil coolers. It is perfectly true that owing to the improvement in bearings and also to the improvement in water jacketing the cylinders the use of oil coolers has largely been discontinued in automobiles. In fact I think it is true to say that there is not a single auto. Company in England following this practice. Our interest in oil coolers is entirely in connection with marine units and of course to a certain extent, stationary engines and tractors might require a similar fitting. It is certain, however, that the volume will not be big. On the other hand you suggested that the tool cost for producing one of these elements would not be high and the different sizes of cooler would ordinarily be built up from various combinations of these elements. Therefore the prospective tooling cost for these coolers is small. If, however, you are prepared to make up an element we will do the tests to ascertain it's heat dissipating capabilities and you then can without much difficulty, produce a range of coolers which should be much cheaper and lighter than anything at present on the market. Yours sincerely, | ||
