I looked at spookshow.net at his steam locomotive encyclopedia and he only had one 2-8-8-0 Mallet listed. The last time it was imported was by Con-cor and was made by Rivarossi in Italy. Before that in was imported by MRC/Rowa. He gave it his highest grade of A. I hope this helps you.

I tried to sell my two cents worth, but no one would give me a plug nickel for it.
I don't have a leg to stand on.
I have an n scale steam loco 2-8-8-0 great northern mallet dc, that I am trying to identify the manufacturer of. Purchased used a few years ago. It runs fine and I plan to upgrade to DCC. any assistance would be appreciated.
