Data from Baldwin Locomotive Works Specification for Engines as digitized by the DeGolyer Library of Southern Methodist University, Volume 53 p. 17. See the Texas Forestry Museum Sawmill database's entry on the B-D mill at []. Works number was 44501 in December 1916.
B-D was formed by E M Decker and E A Blount to operate a sawmill in Cherokee County north of Alto, Texas (southeast of Dallas, north of Houston). From 1908 to 1922, the mill processsed cut and finished pine, gum, hickory, and white and red oak. The small logging Prairie served the 8-mile (12.9-km), 35 lb/yard (17.5 kg/metre) tram road. In 1917 the company was reported to have 125,000,000 feet of timber available for harvest. At the rate of 75,000 feet a day, the reserve would be depleted in 5 2/3 years.
