August 25# 1944 .'j Major <j Kw ith Browning, Heekin Can Company, Park and Forest Avenue, Norwood, Ohio. Dear Major Browning: I am attaching two copies of a report of a survey recently made of the Norwood plant of Heekin Csn Company. For our oWn convenience of accounting, I am also enclosing a covering invoice. I believe that the report will be quite clear, but if any questions arise after you have had an opportunity to read it, please do not hesitate to call me. Cordially yours, ef Fnc. S o b e r .
