This compact oil pump jack is sculpted to sit directly on a layout or small diorama base. The skid-mounted unit includes a walking beam with horsehead, an A-frame support, gearbox and a small operator shelter. The simplified forms make it easy to weather and finish for an industrial vignette beside tracks, tanks or service roads. The piece is supplied ready to place on your baseboard — the low rectangular base allows flush fitting into terrain or on a concrete pad. For very small reproductions, consider strengthening the ladder and rail elements before final installation.
