Just to update this thread:
George/KBC was nice enough to contact me and provided some articles and information regarding the Pisces II steam engine. The operating pressures and the RPMs that this engine needs are beyond making a simple "hobby' type engine setup. Far more than I care to tackle. I would have thought about attempting to make the engine, but the articles showed few or no measurements for the components for the Pisces II. That's OK. I learned about this interesting, and highly specialized design.
Thanks, George, for all the kind help that you offered.
