Interesting. Floating sideframes. Cast. Neat concave worm gears. Certainly no apparent way to connect armature shaft to worm shaft. Must have been a special gearbox to make up for the shortness of the armature shaft compared to the worm shaft.

Wonder what the trick was to actually, well, MOUNT this into something.

Okay. i'll play:
This is advertised as Lobaugh, but I am not at all sure. Doesn't look like Thomas, either, and definitely not an import.

In 1949 Thomas did make a 3-dome tank car. Unable to find a photo. However, they did NOT come with Athearn trucks.
I probably have one of those frames around here.
