| FRANK L. SESSIONS CONSULTING ENGINEER ROCKEFELLER BUILDING CLEVELAND, OHIO May 9, 1927. Mr. A. {Mr Adams} J. {Mr Johnson W.M.} Ashdown, 21 Barton Road, Letchworth, Herts, England. Dear Mr. Ashdown:- I recently used the Ashdown Rotoscope which I purchased from you to observe the fuel mixtures in a glass intake manifold of a Buick automobile engine that was being operated in a demonstration before the United States Federal District Court here in Cleveland in connection with a litigation involving an intake manifold patent. Mr. Claude E. {Mr Elliott - Chief Engineer} Cox, Director of the Commercial Engineering Laboratories, 4612 Woodward Avenue, Detroit, exhibited considerable interest in the instrument and I have given him your address and that of your Sales Agent, Autocar Auxiliaries, Limited. He may write you about purchasing one of these instruments. Yours very truly, FRANK L. SESSIONS. FLS {F. Llewellyn Smith - Frames} :EH | ||
