Data from Baldwin Locomotive Works Specification for Engines as digitized by the DeGolyer Library of Southern Methodist University, Volume 36, p. 160. Works number was 34921 in July 1910.
Fraser River Lumber Company, Ltd bought this wood-burning logging Prairie tank for its British Columbia operations. It was required (in the specs, at least) to scale 6% grades and negotiate 35-degree curves.
The 2 was donated for display at Courtenay, BC in August 1960.

This logging Prairie was bought by the Canadian Western Lumber Company, but it was lettered for the enterprise that bc.memory says became the largest logging company in the British Empire (at a time when the sun never set on the Empire, y' know). Comox logged the forests between Comox and the Campbell River and delivered the timber to the CW sawmills at Fraser Mills.
The 3 operated for Comox during its entire career and was scrapped in Canada in 1944.
