While I have always thought these are cool I have never seen one available.  That is until this past weekend where I saw one sitting on the floor at an antique shop.  When I tried to pick it up to look at it I knew why it was left on the floor!!!  It is in great shape, but does not have a key.  I hope it has it guts inside.   Does anyone know how to get a key?  I reached out to someone on this link
