I have this loco. They, and the Dreyfuss version, are just fine so far as they go. Not up to later Wms brass standards (different builder); a bit delicate. The flywheel is no big deal - better if you have one, but ERR Cruise Commander can handle that lack.
In other words - they're like an old Fiat 124 two-seater - if you are careful and understand their weaknesses they can be a bargain. The boiler detail is good. Add a little skirting on the high-pockets tender.
Not for kids, if you want them to stay together. Adults - no problem.
