Not as rare as the Hofner, and not complete, but...
I bought (from this very forum) the battered remnant of an Ormston-Burns EUB. It does play, and the neck, pup, tailpiece and bridge are original. I knew it was a bit unusual at the time, but I thought that it would be one of maybe 100 originally made. Nope. Apparently, they made maybe six or seven - nobody is quite sure.
