National advertised this as “The Rig that Displaced The Old Standard (wooden) Derrick.” These and similar rigs were widely used to drill shallow holes until they themselves were displaced by portable spudders in the 1920's.
Unlike the others, this rig was still in use until 1972. The Woodcock Brothers of Bradford, Pennsylvania used it to drill 39 wells to an average depth of 1600 ft., between 1960 and 1972, when it was used by the Pennzoil Company in breaking ground for their Houston office.
