I have a mate that just inherited a mint Gibson Kalamazoo acoustic, that his grandfather claims he purchased in the 1930's. It's basically all original and pretty much never played. It says Kalamazoo on the headstock. has a number printed inside the giuitar on the neck, has a sticker inside saying Made in Kalamazoo, MI
What might something like this be worth? I'll post pics when I can in a couple of weeks after exams.
