I was in Jerome, AZ, looking around the local museum, and found a corner of a room with info about the railroads. One photo caught my eye - a 4-6-0 of the Arizona Extension railroad.
That sure does look like the ET&WNC 4-6-0 modelled by Bachmann, otherwise known as the ten-wheeler. It’s standard gauge, so if you had a Bachmann 4-6-0 sitting around, you just have to cut the cab down a little and move it back, and maybe replace the stack. Perhaps add a little to the height of the tender. And there’s your 1/29th 4-6-0.
Here’s a larger varsion of the photo: Arizona-ext-ten-wheeler-jpg
