Original oil and gas trade magazine vintage ad for SARGENT ENGINEERING CORP. Main office and plant was located at 2533 East 56th Street, Huntington Park, California. Introducing Rodless Oil Well Pumps. Proud to introduce a new, hydraulically operated, down-hole pumping unit. Simple in design, the new Sargent Rodless Pump incorporated standard rod pump ideas and parts to assure long, efficient pump life and to minimize repairs. This unique old 1954 two-page petroleum oilfield pumping equipment magazine advertisement would display beautifully matted and framed.
