1930's/1940's Chicago Made Mystery Guitar

Thought I would put up a quick post of this guitar as it was a bit of a mystery.  She just went off on the auction block and there were a lot of questions and comments about it.  It has a bit of a Regal look to it, but the binding looks like an Oahu trait which would suggest it might be Kay made, then you look at the headstock and it says Harmony.  No one has been able to pin it down, but one thing we can probably be sure of is it was Chicago made.  The guitar is in amazing shape for its age and needed some setup work to get it into top shape.

this guitar is surrounded in a really cool checkerboard binding - even has a strip running down the center back seam which is something you don't see very often
