Here is a neat Oscillating engine I saw on an exhibitors table at the Black Hills Model Engineering Expo in Rapid City SD this past month. Owned didn't know the source of castings except he thought that they originated in Western Canada. The flywheel was in the 7-9 inch diameter range and the finished engine somewhat over 12" high. If anyone in that part of the world that knows of the casting source I would appreciate knowing who they might be or have any contact with anyone that might know source. Appreciate any insight anyone could provide. Thanks. Bob— Hope I got the right pic attached.
