This is a realistic model steam engine that looks the part. Every aspect of this SE-03 has the best finish and detail of any model. And the price is not unreasonable for the quality provided. A certain German steam engine provider for nearly the same price uses stamped sheet metal parts, a non-working govenor, and no ball bearings. On this one, the flyball governor actually works. My only negative is the pressure gauge. It is not up to the detail and quality of the rest of this engine. Worse, it is a press fit, and when steam pressure begins to build, the gauge rocket launches into the atmosphere. This one item needs some redesigning. If the pressure gauge were up to the level of the rest of this model, I would rate this as the best boiler/steam engine commercially available. And get the workshop. Makes a great combo!
