Data from Baldwin Locomotive Works Specification for Engines as digitized by the DeGolyer Library of Southern Methodist University Vol 48, p. 287. Works number was 40620 in September 1913.
An indication of the somewhat primitive nature of the road's construction shows in the 25's specification note: "Locomotive to be strongly built for use on 10% grades and rough hilly country." It had to be light enough to travel on 25 lb/yard (12.5 kg/metre) rail.
After the RR&LC closed in 1931, the 25 was sold to Jackson Brothers Lumber Company.

The Baldwin specs identify the buyer of this wood-burning Mogul as North Carolina's Surry Parker Lumber Company (operator of the Surry, Sussex & Southampton narrow-gauge line). Al Weber's number-by-number accounting of Baldwin's production records the operator as the Roanoke.
The RR&LC was described in 1922 as the "one of the oldest firms engaged in the manufacture of North Carolina pine" in northeastern North Carolina. It had mills at Washington, NC (rough lumber) and Money Point, Va (rough and dressed lumber). Some of its subsidiary private railroads were the Bayside & Yeatsville Beaufort & Pamlico (1900-1905)
We know little about this engine. The specs say the fuel was "wood of poor quality".
