The metal columns on the front of the building have been painted over so many times that I could not say for certainty which company built them. At first, it looked like Texas City, and there was an ironworks in Corsicana at one time. Their products included castings for the building industry. Closer looking makes the name look more like Pennsylvania, however, and there was an Erie City Iron in Pennsylvania, but no indication they made building parts. Their products included engines. Other guesses include Texarkana AR.
