I am trying to identify this engine. My dad acquired this engine in 1968 then painted it and set it next to the fireplace as a house ornament. Visitors always asked about the strange little coffee grinder. The crankshaft was badly repaired at some point so I made a new one years ago to get it running leaving the old paint job. I tried to make it look like a coffee grinder using a coffee can for cooling and some creative brass pipes to add character. The gear driven make and break ignition came with it but is clearly an add on. There is a ground down post on the piston that originally worked as a the ignition. It has similarities to a Pacific model I’ve seen advertised. The seller said it came from England and ran a small printing press, but that story was past down through his grandfather.
