"The engine does not follow a specific prototype, but rather incorporates features from several different roads."
If memory serves...actually it has a B&O prototype, and is not a bad model of it, if not encrusted with details. I forget the exact B&O class or loco it follows. The basic mechanicals were used under their very early - non-Samhongsa - Wms J3 NYC Hudsons. All of these locos are rather delicate, but can be interesting projects, if their mechanical and detailing are acknowledged. They are handsome. I have never equipped one with an ERR Cruise Commander, for example, but I imagine that their running characteristics would improve.
I have one of these B&O's, but I can't lay my hands on it.
