This was from the starter set. Works great, sound and smoke. I had it apart to lube it up and stripped one of the two posts near the steam chest when reassembling (was a bit aggressive with my screwdriver)
Doesn't affect operation at all, and no visible issues on the body of the engine or tender. I've already got one of these, tried to sell in e-auction site but buyer returned it on account of that one stripped screw.
Will trade for some GarGraves phantom 054 or 072 track (could use a loop of each) as well as a bunch of straight, or sell for 125.00.
