| HARRISON RADIATOR CORPORATION LOCKPORT, NEW YORK STD June 19, 1934 Mr. W. A.{Mr Adams} Rowbotham Rolls Royce Ltd. Derby, Derbyshire England Dear Mr. Rowbotham: In your letter of June 4th, with which was enclosed a print showing the dimensions of a radiator in which the maximum depth of 3.3" is given, wish to advise that unfortunately we do not have dies or machines available for making a core of this depth in the new 20 x 55 constant having the flat water passage. However, we are preparing designs so that dies may be made up to produce a core of this thickness. If there is any possibility of using a core 3-1/2" deep we would be in a position to supply one at an earlier date than one of 3.3" depth. In connection with the corners, of course we will arrange to cut them as per your drawing. Yours very sincerely L.P. Saunders LPS:C L. P.
