| Messrs. Rolls-Royce Ltd. Derby, Derbyshire, England -2- April 9, 1936 Trust this will explain this apparent discrepancy satisfactorily. The situation in respect to our 18 x 62 constant core at present is not quite clear and would prefer to defer answering your question in this connection until a later date. This matter is now being worked on over here and just as soon as additional information is available, will arrange to keep you advised. The question of Oil Coolers, etc., etc. has, I believe, been answered in my last letter to Mr. Day. We have started production in a very small way on this new design and do not feel that we have sufficient experience back of us from a production point of view at this time to take on any new accounts. Mr. Day has been supplied with performance data and we are at present producing in our research furnace about 50 units per day. Yours sincerely, HARRISON RADIATOR CORPORATION LPSaunders. L. P.
