Data from DeGolyer, Volume 65, pp. 243+. Works number was 53695 in September 1920.
Locobase 13177 describes JLRLC's large timber business and shows a Mogul that served the 150 miles (242 km) of logging roads. This logging Consolidation followed that engine and a Baldwin Prairie.
The 105 was later sold to Arkansas Land and Lumber. AL&L sold it to Sumter Lumber Company in Sumter, SC.
