This is the third and final of my recent PSE Polish Steam Engine purchases. This beam model and the vertical steam engine posted a few days ago were both Christmas presents. This one didn't make it until a couple of days after Christmas. Each engine I have purchased seems to be getting a little better at running on low pressure right out of the box. This one runs very smoothly right out of the box on four psi. This is the only one of the three that I purchased with the patina-ed finish. I think it suits this particular model, but I still like the polished ones better!
They have quite a few other models available in their online catalog, but these will have to suffice for now.
