| X1278 HARRISON RADIATOR CORPORATION LOCKPORT, NEW YORK December 10, 1935 Mr. C. S. Steadman, Experimental Department Rolls-Royce, Limited Derby, England Dear Mr. Steadman: Ref: Hs{Lord Ernest Hives - Chair}/Std. 11/KW In answer to your letter of November 26 wherein you inquire concerning the relative value of the Chausson Gallay core in comparison to the core now made by Marston Mark VI type, am unable to say definitely the amount of increase in dissipation the Harrison core puts out without having a block for test purposes. The print attached to your letter #40731 shows a Modine type of core, and comparative tests run here with a core of this description in comparison with the Harrison core shows our core to be superior from a dissipation point of view, and in addition we have a weight advantage. If you are sufficiently interested to forward us a 17-1/2" square section of this core, we will be pleased to test and report results to you. In connection with the bursting of viscon type of oil regulators, we have no difficulty from a bursting point of view in this country, and if units are being made up for you would suggest that the difficulties may be due to structural design weaknesses, which we encountered in the course of our development work. If you care to let us know the precise nature of the difficulties you have encountered, we would be pleased to advise you to the best of our ability as to how to overcome the trouble.
