I recently purchased what appears to be a 1937 Kay Blond M-4, based on photos I have seen across the web. I do not see a Kay label on the inside, but instead a strange label has been placed possibly over it. I will post a photo of it. I did find a handwritten number inside, 1471 I think. I would love to hear if you think this really is a Kay and what the penciled number means. Also, which parts have been replaced. Thanks!
