When Southwest Lumber Mills bought out the Saginaw & Manistee Lumber Co. in 1953, they renumbered the "25" to "2". One silly story is the engineer hung his water bag on the side of the cab,and wore of off the "5", so they left it as "2". Note that the original Baldwin spot plate is on the smokebox with the "25" covered by a "2". When the engine was put on display at the mill in Flagstaff in 1966, returned to its original number - "25".
Yeah...right.
Anyway, #2 - 25 never operated with the small slope back tender that is displayed with. It is the same tender seen behind Apache Ry 300, and I have serious doubts that tender ran behind 300 either as it was too small to be of much use. There is a shot of this tender behind Malley #4 before the side tanks and rear fuel bunker were removed and a larger tender was applied.
The 25 has a unique story in that it has spent its entire existence hauling log trains in the Flagstaff area.
