I've got a locomotive that would be complete with a gas tank. I found it on spookshow, still can't locate that part. Thanks, Jim
I have a surplus GP7/9 tank (one with the two roundish air tanks) that I don't need. It also fits the GP30 shell as I remember. If you piled enough putty on it you could fill in and file it right down to match if you wanted. http://www.spookshow.net/loco/files/arnoldgpold.jpg
