This is a Kawai acoustic archtop that I got off ebay that I can't identify. The store I bought it from believes it to be from the late 60's or early 70's. It is a bolt on neck, I have seen other Kawai archtops with the same neck - headstock, inlays, and truss rod - but this is the only purely acoustic one I have ever seen.
I removed the pickguard and replaced the bridge (I bought this guitar foremost to play it, but kept the original bridge which needs a new saddle.) Here's what it looked like before:
I have more pictures, let me know if you would like to see it from any other angle.
