I've been chatting with the guy and so far it looks like a hiwheel boneshaker replica from when HiWheel used to be in Ohio. They retail new for around $900 USD. He wasn't really sure when I first talked to him, but the info he's given me so far, I'm pretty sure that's it.

This particular one is a 48" model.
