Original oil and gas trade magazine vintage ad for LEE C. MOORE CORPORATION. Main office and plant was located in Tulsa, Oklahoma. Other offices were in Houston, New Orleans, Centralia, Odessa, Midland, Dallas, Great Bend, Casper and Pittsburgh. New Mast Design, especially suited for offshore drilling. To meet the special requirements of offshore drilling, Lee C. Moore engineers have designed a new Braced A Frame cantilever type mast. This unique 1957 old oilfield petroleum drilling industry equipment magazine advertisement would display beautifully matted and framed. Nice graphics.
