That's some mighty fine CAD work you do there Chris! And a lot of it. I'll bet your tools are getting jealous of all the time your spending with the computer these days Kim

very impressive. I saw one (tracked style) at the Milton Steam show a few years and thought it would make an excellent model. My hats off to you for doing instead of thinking about it
Not familiar with that show, just looked it up, have to see if I can get there next year, only a few hours from here!
The advantages of thier arrangement are several: - the throttle can be left wide open, since the reversing lever has a graduated set of openings that allow the engine to be run slow to fast, depending how far in one direction the lever is moved.- in the center position, there is no steam flow to the cylinders at all, stopping the engine.- for the slew engine, the center valve length is set up so that in the middle (stopped) position, both cylinders are connected to exhaust, so the engine freewheels, allowing the turntable holding the boom to drift to a stop
