Original oil and gas trade magazine vintage ad for MID-CONTINENT SUPPLY COMPANY. Main office was located in Fort Worth, TX. Rig handled heavy loads with ease on 23,400 foot well. That is the record of the U-1220-EB Electra-Flow Drawworks on Great Western Drilling Company's Rig 44 in Pecos County, TX. This unique 1959 old oilfield petroleum industry drilling equipment magazine advertisement would display beautifully matted and framed. Nice graphics.
