Unidentified engine skeleton

While doing some delivery work today, I found a guy that has engine skeleton. He pulled it out of the woods on his Dad's property, a few years ago. He said that he remembers that his Dad got it from a scrap yard, many years ago & made a wood splitter out of it. "> Fortunately, he didn't screw it up, too bad! All that remains, is the cylinder & the flywheels & crank...everything else is gone! After he pulled it out of the woods, he cleaned it up, painted it & covered it up. (He said there was remnants of red on the cylinder, but he painted it orange.) There are no identity markings & he has no idea what it is/was. (I didn't have my camera along, but will try to get some pics in a day or 2, if needed.) The casting numbers all start with the letter L. The flywheels are L2 & are about 37" in diameter with a 3" face. The cylinder & sub-base are one large casting & has the casting number L1. The cylinder is about 6" X 20". The numbers 207 & 275 are stamped on opposite sides of each other on the crank journal. The crank is about 2" wide & the journal is 2-1/4" wide. This appears to have been at least an 8hp engine. There is no hopper & I couldn't see any holes to bolt a hopper to the engine. However, there's a flat space with a weird shaped opening on top of the cylinder. Like I said, I'll get some pics & post them ASAP. In the meantime, does anybody have ANY idea what this is??? There are no cracks or breaks that I could find, the flywheels are straight, but the governor weight has been welded, & is salvagable. THANKS!!!
