| THE PRATT & WHITNEY AIRCRAFT CO. HARTFORD, CONNECTICUT U.S.A. CABLE ADDRESS "AIRCRAFT" January 24, 1934 Mr. W. A.{Mr Adams} Robotham c/o Detroit Athletic Club Detroit Michigan Dear Mr. Robotham: I am sending herewith enclosed two blueprints, F-30398 and R-30157, which we have found, showing a typical test house unit in more complete detail than the factory layout which I showed you the day you were here. I presume these will be more useful to you than the other. They were made up with the purpose of recommending a test house for the Canadian Pratt & Whitney and various overhaul stations and are typical of the units which we use. I hope they will serve to give you the information you desired. Very truly yours A.{Mr Adams} WILLGOOS Chief Engineer AW:I NRA MEMBER U.S. WE DO OUR PART | ||
