Geiser Manufacturing was formed in 1869 out of earlier companies that built farm machinery. At the time this tank engine was produced, Geiser occupied two large plants in Waynesboro, PA. Although operating on the standard gauge on 50-80 lb/yard (25-40 kg/m) rail, this was a tiny engine that nevertheless had to scale grades of 90 to 110 feet per mile (1.7 to 2%) and negotiate curves as tight as 100 feet radius. Some of the curves could present 45 degrees of radius on a 1/7" grade. This may explain the relatively large firebox and certainly justifies the 5 to 1 factor of adhesion.
Purchased by Emerson-Brantingham in 1912, Geiser was later sold again to a consortium based in Waynesboro in 1925, but by 1939 the company was bankrupt and all of its assets up for sale. The entire manufacturing plant went up in flames in 1940, the glow of which could be seen for 40 miles.
