MINT.  This beautiful engine has never been run in practice, other than some minimal testing.  It looks like the tender has never been unwrapped, and obviously the wheels have not been attached.  I did not remove the plastic from the tender in order to preserve it's pristine condition, and the video was made with a 'guest tender' from another set. 

The locomotive runs smoothy and powerfully at high and low speeds.  See the video.

Small parts and original paperwork are included.

The box shows some minimal shelf wear, but everything inside is pristine.
