There are pipes and a mount for a second air pump, but I didn't want to climb up on the locomotive to take a closer look, in light of the rather precarious perch the locomotive has on the crude piece of track. The other two are apparently still in Cottage Grove, Oregon. This locomotive looks like it has been heavily canibalized. One of the two air pumps has been removed. The pieces of rail under the rear truck are tipped over.
All parts are still there, drive train is complete, and amazingly, the generator is still there.
Previously, it was on display in the Woodland Park Zoo in Seattle. The boiler is off the frame and is sitting on several ties nearby. The tender is nearby, and is off it's trucks, which could be explained by the same transportation issue. The front of the smokebox is missing as well, and I don't see the generator, headlamp and whistle anywhere.
