Class Details by Steve Llanso of Sweat House Media

Class 1 (Locobase 13484)

Data from DeGolyer Library, Volume 32, p. 292. See also the history of Wendling in http://ths.sps.lane.edu/english/Period3/Nick/, last accessed 22 November 2011. Works number was 32943 in August 1908.

This was the first Baldwin sold to the big lumber company that Robert Booth and George and Tom Kelly established in Oregon in the town they named Wendling in 1899. Wendling was the headquarters of a large timber empire that harvested throughout the Mohawk Valley of Oregon.

This logging Prairie arrived on the property as a wood-burner, but was converted to oil burning in 1913.
