The Angelina Hardwood Sales Company of Lufkin, in 1947, was preparing and finishing rough lumber, then marketing it. The Gulf Coast Lumberman, in January, 1947, wrote an excellent article about the plant. George Henderson proudly showed his plants to members of the Texas Lumber Manufacturers Association in February, 1947.
According to the Directory of Texas Manufacturers 1956-1958, George H. Henderson was still managing operations and directing more than 100 employees. In 1963, reported the Southern Lumberman, the operation had a dry kiln, planing mill, and produced machined or semi-finished dimension, thresholds, and glued-up treads.
In 1966, equipment consisted of three lift trucks, three dry kilns, one hog, twenty-five electric motors, two compressors, four molders, and two lumber trucks. A woodworking plant was added by 1976, which worked with only oak. That same year more than eighty employees were working for the company. In 1987, the mill was manufacturing truck and trailer stock.
