Zwack Inc.

Zwack Inc. is a fire apparatus dealer and former manufacturer located in Stephentown, New York. Zwack was formed in 1970 and mainly built pumpers & tankers on commercial chassis for departments in central New York State (as well as a few depts. in New England). Apparatus production is believed to have stopped in 1980. The company is still in operation as a custom fabricator and manufacturer of sand and salt plow trucks, and also acts as a dealer for W.S. Darley & Company apparatus.
One source gives the company name as the Zwak Manufacturing Company and suggests that operations started in 1960.
