The middleweight double straightbars came in two frames the early ones had 1/2 disconnected straight bars..and later'typhoon' frame had 9/16 tubes connected into the rear off the frame and they are called continuous frames..my favorite for sure, and a lot of them were used for early mountain bikes and klunkers..tornados and skippers are the rarest but the typhoon is cool with the welded on kickstand..just more common
Sorry, but no. DO some research and you will know this is off a steam, diesel or early gas engine. Water wheels had no fly wheels. I have been to TONS of engine shows around the midwest for 50+ years. These two piece fly wheels were used on old fairbanks-morse engines that were built in beliot wisconsin. So their you have it.
