Data from Baldwin Locomotive Works Specification for Engines as digitized by the DeGolyer Library of Southern Methodist University Volume 43, p 269. Works number was 38972 in December 1912.
Greenleaf Johnson's second new purchase from Baldwin was a Consolidation with a slightly larger boiler and grate and one more driven axle than the 2-6-0 that went into service in 1906 (Locobase 13005).
It's not clear if Greenleaf Johnson was simply renamed Greenleaf Hollister; in any case, the 10 was renumbered as 1. The latter owner disposed of the 10 in 1916 by selling it to the Dismal Swamp railway as their #1. Dismal Swamp later sold the 1 to the Richmond Cedar Works.
