Preserving Pump Jacks

An Iowa man has collection of 60 unique pump jacks, including a walking beam pump jack.

Walking Beam
This walking beam pump jack, dating to about 1900, tells a little-known chapter of a company later famous for its tractor. Letters at the top of the beam reveal the manufacturer, Waterloo Gasoline Engine Co. The unit is powered by a Beats ’em All gas engine.
