1920s Schwinn Motorbike project

Rare 1920s what I believe is a Schwinn Motorbike. Frame seems straight and solid. Original paint? I believe this would have had the narrow 28" wood metal clad wheels . Unfortunately what you see is what I have .Obviously a major project, missing parts, needs repairs and restoration. However if a Schwinn Motorbike a very desireable antique worth the effort. As is decor or restored still beautiful piece to me. This has been hanging in my barn for years and I'm not overly familiar on the details or specifics. I'm hoping one of you experts can shed some light on it. See pics for details.  Questions or information to share, please let me know.  Thanks  UPDATE.. I kind ebayer says it maybe a 1935 Colson. I believe he maybe right. Please do your own research as I'm not sure. Thanks
