Data from DeGolyer, Volume 11, p. 254. Works numbers were 6978, 6991, in October 1883 and 7047-7048 in November.
A quartet of wood-burning Ten-wheelers constituted a large class of locomotives on this central Florida skinny gauge. 11 suffered a premature demise in an SF roundhouse fire on 4 January 1886. Unlike earlier SF engines, the other three were big enough to be converted to the standard gauge in 1891.
The 10 later went to the Savannah & Statesboro. By 1906 it served the logging industry on the Porter-Wadley Lumber Company (sold, apparently, through a Baldwin extra order on 15 February 1906) and later on the Alexander Lumber Company's rails as their #4. 12 had a second career with the Charleston Mining and Manufacturing Company. 13's sale through a Baldwin extra order on 1 March 1905 was concluded with the Dutton Phosphate Company of Clark, Fla.
