A cool old water pump made by the Silver & Deming Manufacturing Co. of Salem, Ohio sometime between 1874 and 1890 (according to the website below). Looks like they may also have actually used it up there at the KQ Ranch at some point.

This company began back in 1854, when Albert R. Silver and John Deming formed a company to make agricultural machines, although the "Silver & Deming" name does not date back that far. In the later history of the company, Emmor W. Silver was a principal; he was perhaps a son of Albert. In about 1874, Silver & Deming incorporated and became Silver & Deming Manufacturing Co. In 1890, the company reportedly split, with one part becoming Silver Manufacturing Co.
