I need help as in, i need help in finding somebody who can build an HO scale model train of Casey Junior from Disney's Dumbo. Not the ride version, but the film version. And I want it to be a full running model. But if there is nobody who can, then I would like some tips on how to build it myself. I already have the electrical parts that I can use from one of my older models. So please. Any help is greatly appreciated. Thank you.
