Here's a little history on your engine.
Vincent Barney in Washington state had that 16hp Galloway in his collection. I don't know where or when he got that engine. When Vincent started selling his collection I got the Galloway for Dave. I took it to a few shows in Oregon, then hauled it back to the 1999 or 2000 Portland Indiana show to deliver it to Dave Rotigel. The blue engine in the photo is a 10hp Holland engine that I also got from Vincent Barney.
