Anyone seen this guitar on eBay, looks nothing like any ObG firebird I've ever seen. So many things wrong with it for an Orville looks very much Korean built to me. May well be a nice guitar as you certainly don't come across many neck thru firebirds but I'd certainly have doubt's it a legit Orville , prototype or not.
