But only if you need that rare, vintage, SCARCE glass knob stuffed up the............smokebox to finish your 100 year old house.
On the engine...no underneath shots, pilot truck bent way back, "cowcatcher" snapped off, push-on stack gone, mangled pot metal piston rod.

BUT! If you want the WHOLE SET for $40, here it is!

Guess:

Some kid pushed the dinner table up against the doorknob, set up all the straight track he or she had, and ran the loco full speed into the door and knob. Would explain missing "cowcatcher", bent pilot truck, and embedded glass knob.
Just a guess.
