Data from Baldwin Locomotive Works Specification for Engines as digitized by the DeGolyer Library of Southern Methodist University Vol 30, p. 158. See also Thad Sitton & James H. Conrad, Nameless towns: Texas sawmill communities, 1880-1942 (Austin, TX: University of Texas Press, 1998). p. 63. Works number was 30152 in February 1907.
Headquartered in Remlig, Texas (to decipher the origins of the town name, read it backward), the AGLC adopted the Baldwin Prairie logging locomotive design for its operations. They proclaimed themselves as Manufacturers of Nothing But Long Leaf Yellow Pine. After some years on the AGLC, the 2 was sold to Martin Wagon Company.
Sitton and Conrad report that like many other lumber companies of the time, Alexander Gilmer used a pay-slip system which operated daily but were redeemed only once a month for merchandise at the company store. Used any earlier, the slips would lose some of their face value and private merchants would discount the slips by 20-30%
