It's a Taiwan cheapie, with what looks like a Savage seat. It's impossible for us to know if the original owner paid the 400 pounds for it, but we can be sure he was majorly ripped off if he did.
What the seller is telling us is that he knows absolutely nothing about this unicycle, and he's looking for a buyer who does as well. And if it's up to him, he'd rather not hear from any of us. 🙂
