I got one!...this Ertl engine seems to be in most demand next to the John Deere model M.
Ertl release these in several batches, each in slightly different color scheme...this is the limited edition 1 of 5000 and I believe it is the same variant St Paul used in the video...it is by far the best looking IMHO.
The Gold tone on the water tank is the only thing I am iffy about, I may wrap mine in thin copper foil to customize the look. I now have all 4 Ertl stationary engine models...I got to get out in the shop and start converting for steam power.
