Data from DeGolyer, Volume 21, p. 238. Works number was 16110 in August 1898.
A small Eight-wheeler, 103 only operated on the L&A for a few years before being sold in 1903 to the Louisiana & Texas and taking new road number 6. The L&T operated the 6 for seven years, then sold it to its most likely owner, given its light-footedness and paid-for status, the Lufkin Land & Lumber Company.
