Data from DeGolyer, Volume 62, pp. 383. Works number was 52820 in January 1920.
Purchaser was the A&NR's parent company, the San Augustine Lumber Company. The superheated steam in this logging Prairie required the adoption of 8" (203 mm) piston valves to feed the cylinders.
In 1945, the A&NR sold the 108 to the Reader Railroad in Arkansas. Thirty-one years later, the 108 moved on to North Conway, New Hampshire to star on the Conway Scenic Railroad. It was later sold to the Blacklands Railroad, Church St., Sulphur Springs, TX, where it is reportedly under restoration.
