Originally built for Larson Lumber in November 1927, this 2-6-6-2 Mallet went to Bloedel Donovan Lumber Mills in Washington instead. Although being standard gauge, it was fairly small for a 2-6-6-2, optimized for logging service. Nevertheless it was much more powerful than the Mallet tanks of the same wheel arrangement then in use by this company. It had drivers of 51 inches and cylinders with diameters of 20 and 31 inches, at a stroke of 28 inches. Later it came to Rayonier, Inc. and still carried the number 14. It was retired in 1964 and scrapped four years later.
