The estate had approximately 20 engines. I could not find any markings on this engine.
There were several catalogs with the engines. I do not know if it is one of these engines or something different.There is a single piston that moves vertically. The flywheel is 4 and 1/2 inches in diameter. The engine is 10 inches tall. The base is 6 and 3/8 inches by 3 inches that does not included the flywheel and shaft that extend beyond the base. There is a valve where the air or steam comes enters.
When connected to air, the machine runs flawlessly. It is in excellent condition. The item "Vintage Steam Engine Stuart Coles PM Research" is in sale since Sunday, June 12, 2016.
