Forget about that engine!
A nice Key AC-3 FP 2-8-8-2 came up for sale on ebay.
Thought I'd check brass trains on it and the gauge is way off. Surprised Key even sold them like that. I think I'll pass on that one! If one had some drill rod in that axle size, it could be redone. I've had wheels out a 'tad' but that looks more like narrow gauge! Surprised brass trains able to sell it at such a high price: I guess those people that are just collectors and don't really do anything with them but look at them, it's OK.
