This way cool instrument came up for auction in February 2011 and sold for $2,150. While the interior of the case is a total knockout (too bad there weren't a couple photos of the exterior) the guitar also sports an interesting custom brass saddle in place of the rosewood bridge.

This rare original model is one of the very first ever made, and it's number (438 is very low since they started at the no. 200) This is stamped inside the neck pocket (See Pics).
