This engine has a carbon piston. 
Bore is 1” and
Stroke 1 1/8”  
double acting D valve on a stellite face.

When tested on Art Gardiner’s water dynamometer in 1973 here are the results:

3.2 horsepower, 
2100 rpm, 
600 psi steam at 600 degrees F
8 foot/pounds of torque and
using 120 pounds per hour of steam.

Which worked out to 352 psi BMEP and 35.8 #/bhp hour.

   

I think this engine has been run at much higher temperatures and the beauty of the carbon piston and valve is that no oil was needed in the steam line. 

Carbon “D” valve.
