The James Morrison Brass Mfg Co. was founded in Toronto in 1864. The business prospered and was able to relocate in 1872 to larger premises on Adelaide Street West. In addition to brass founding and finishing, the company did business in engineers, steamfitters, plumbers and gas fitters’supplies. In 1891, the firm moved again to a new factory in Mimico. At that point in time, the comopany was employing 150 people. In 1930, the company was acquired by the Equitable Securities Corporation of Montreal & Toronto, becoming the Morrison Brass Corporation. It was one of only four Canadian companies making cast iron, steel & brass valves, high quality brass & bronze for pulp & paper plants, locomotive & marine equipment, plumbing, heating products, and gauges for steam, air & water. The last reference I can find about the firm is its involvement in a 1956 scandal investigated by the Ontario Securities Commission. Apparently, sometime in the 1960's it was acquired by the Cincinnati-based Luckenheimer Valve Company, which itself fell victim to a hostile takeover from Condec in 1968, and then in 1994 became the Cincinnati Valve Company.
