10" l x 14" w x 27" h, 55lbs.
Made from an antique Leiman Bros cast iron air pump. This air pump was manufactured in Newark, NJ. Patented June 1904 and March 1908. The drip oiler is still there. An explosion-proof light added. This pump was salvaged off a late 1800's tug boat that worked the lower Columbia River. It is possible this pump could have been used to supply air to an early brass diving helmet.
