I initially thought this rusty little Heisler was Broughton Lumber #2, missing its characteristic onion stack. However, Dr. Raimund Lierhammer has pointed out that it is, in fact, Pickering Lumber Corporation #1 with its tender set aside. My thanks to Dr. Lierhammer - I always welcome positive and constructive feedback on this site.
The locomotive was built by the Heisler Locomotive Works in Dunkirk, NY, as #1 for the Sunset Timber Co., in Raymond, WA, in 1913. It was sold to the Demsey Lumber Co., in Hamilton, WA, then to the Standard Lumber Co., in Standard, CA, before that firm was consolidated into the Pickering Lumber Co.
