Class Details by Steve Llanso of Sweat House Media

Class 4 (Locobase 15048)

Data from Roy V Wright (Ed.) 1912 Locomotive Cyclopedia of American Practice, Sixth Edition (New York: Simmons-Boardman Publishing Company, 1912), p. 167.

Gulledge Brothers had lumber operations in several state, so Locobase is unable to pin down where this little logging Mogul worked.
