High Quality Content by WIKIPEDIA articles! The American Brass Company was an American brass manufacturing company based in Connecticut and active from 1893 to 1960. The company`s predecessors were the Wolcottville Brass Company and the Ansonia Brass and Battery Company. It was the first large brass manufacturing firm in the United States, and for much of its existence was the largest brass manufacturer in the country. It was purchased by the Anaconda Copper Company in 1922, and merged into Anaconda`s other brass manufacturing concerns (losing its identity and name in the process) in 1960.
