You say it turns over by hand easily and smoothly?

Seems to me that there must be something in the steam line or timing that would be seriously interfering with air/steam flow!

I do only see an input steam line to the first cylinder and only see an exhaust line from the last cylinder, so near bottom of each stroke there must be porting that that feeds exhaust to the next cylinder in line like a proper compound would do, only with all cylinders the same size, this engine is set-up as simple as opposed to compound.

Rotating the two linkage rods that run the length of the cylinder block, on either side of the cylinders, would seem to be the "valves" that switch between steam feed or exhaust, while the plunger rod that is also part of that same linkage and comes in from the side of the block near where the oiler reservoir is located, must switch the feed between the two long linkage rods?!?!

Still not quite picturing how this is supposed to work, but if it in fact can work, it must be able to do so at reasonable pressures.
