I believe Rob English made a
few, but it'll probably cost you an arm and a leg for that custom frame and wheelset(which, by his reputation, may be worth your arm and leg...). Not sure if it's worth it just to change tubes though. Certainly looks unique, and could probably be built very stiff when using the right tube diameters, which I'm sure Rob went through the troubles to make sure it's correct.
If you have a friend with a brazing torch and a few weekends, you could probably make a similar frame for $300, but you'd have to figure out where to source the rear hub, or how to machine one yourself. If you're okay with a lefty front and a righty rear, you could get a lefty hub for the front, but I don't know of any righty rear hubs.
