This trade show photograph shows a fine collection of pumps (Oshkosh handpumps, trahern hand pumps, red jacket hand pumps, and star pointer air lift water systems"). Signage also notes that the company is also a jobber of plumbing, heating, & mill supplies, pipe fittings, brass goods, and hose.
The company is not listed in Romaine, nor does OCLC note any catalogues by the company. We are aware of at least one catalog produced by the company on the market as of this writing. A quick web search turns up advertisements for the company from 1887 through 1916.
Trade show photographs tend to be fairly scarce, and are excellent supplements to trade catalogues which are often only illustrated with cuts or half tones.
