| HARRISON C. S. Steadman Derby, Derbyshire England September 9, 1938 Page 3 As stated previously, we are interested in pressure systems and are seriously considering an all-brazed copper radiator, experimental samples of which have been made; although at present we do not quite see our way clear to making this a production assembly. This particular radiator will stand pressures of at least 250 to 300 pounds per square inch. Kindest personal regards, Sincerely yours L. P. Saunders LPS:BKW P.S. - For your information, we are in the process of building another car tunnel on a very much larger scale than the one which has been used successfully for the past few years. The old one had an electrical input to the fan of 125 horsepower and the new one will have approximately 600 horsepower. Just as soon as the schematic drawings are available and the first tests are run off proving this equipment, will send you further details which, no doubt, you will find interesting. L.P.S. | ||
