Donna Harrison-Rodeghiero provided this image of Frisco Ten-Wheeler No. 1103 taken at Enid, Oklahoma on August 29, 1939 by an unknown photographer. Coming from ALCo's Schenectady works in 1907, the 12 members of class 1100 were soon superheated by the Frisco's shops. They had 69-inch drivers and 21x26-inch cylinders, and carried 200 p.s.i. of boiler pressure. As rebuilt with 405 square feet of superheating surface, they had 2148 square feet of evaporative heating surface and nearly 48 square feet of grate area. They developed 28,250 pounds of tractive effort and weighed 188,850 pounds. Some members of the class, not including No. 1103, remained in servive up to 1951.
