​​​​Original oil and gas vintage magazine ad for CUMMINS ENGINE COMPANY, INC in Columbus, IN.  Twice custom-built diesel engines.  Rugged, lightweight, high-speed diesels perform better because they're built under the strictest quality control methods.  Each engine is run in on the test block.  Then it is torn down and carefully re-inspected, and then re-assembled and tested again.
​This 1951 unique old one page petroleum drilling power trade advertisement would display beautifully matted and framed.
