| -2- Concerning the oil cooler which you submitted, this was tested for us by Messrs. Clayton Dewandre Ltd. against two of our own coolers and the results are attached. Here again it is seen that from the point of view of heat dissipation and weight, the Gallay cooler is inferior to either of our own coolers, although it shows a better oil pressure drop characteristic. We regret to say, therefore, that these tests offer no inducement to us to change over to your products. If you will inform us whether you require any of the test blocks which you have sent us, we will arrange to return them to you. Yours faithfully, FOR ROLLS-ROYCE LIMITED. | ||
