I finally did the work necessary to get the Bachmann Vanderbilt tender to work with the 4-6-0. Here is my version of Bullfrog Goldfield #12. I finally got the tender rewired and mated up with the 4-6-0. It now consists of the Bachmann Vanderbilt tender attached to the 63 inch driver chassis and mounted on the low boiler body.

Eventually I have to move the bell and complete the striping.
Excellent, you've captured the look of the prototype to a tee. :)
