This is a Symplexophon that came up on Ebay last week. Take a good look because I genuinely don't think there are many of these around. It sold for just $114 US (60) so somebody got a great bargain and a piece of history too.

This Symplexophon is an early instrument made in around the 1870's.  It was called a harmonica with keys or Wind Accordion.  This one is red colored wood with leather around it.  The word Symplexophon and the numbers 1-10 are gilt, along with Made in Germany and Registered. There are two white metal keys each imprinted with Germany and on the other side are 10 keys.  Two are missing the white glass and black leather parts.  Please see pictures.  There are cracks in the wood and some of the leather is beginning to peel.  The tops of the keys have stuck to the leather in places.  I don't know how this works but it has a wonderful look and is unique.
