From around 1972 through 1979, the headquarters of Gas Turbine Division (a.k.a. Gas Turbine Systems Division and Combustion Turbine Systems Division), had been located in rented space in the renovated Baldwin-Lima-Hamilton Building (vintage 1920s) in Eddystone, PA, just south of the Westinghouse Lester factory. The gas turbine division operations occupied the top 4 floors of the 7-floor office building (known as The "A" Building), while the rest of the building was occupied by Westinghouse Steam Turbine Engineering and other support groups.
