Data from Baldwin Locomotive Works Specification for Engines as digitized by the DeGolyer Library of Southern Methodist University Volume 49, p. 17. Works number was 33530 in July 1909.
When Brooks and Scanlon bought a company in 1908 in Stillwater, BC (on the mainland northeast of Vancouver Island), it took possession of John O' Brien's railway, which he had operated since 1900. The merged assets logged south of the Powell River.
This small, wood-burning Mogul was the lowest-numbered engine in the company.
After about 15 years of operation, the BSO saw its structures consumed by an accidentally lit fire. Essentially ruined, the company sold out to Powell River Company in 1929.
