I just added my Gretsch (http://gretschpages.com/gui...) to the DB, but I don't know much about it, and there aren't any similar models, so I wanted to also post here, and add a few more pictures. It is a Jet 21 archtop, Serial # 3628. Based on my readings here, I think that puts in about 1950. The fretboard inlay is simple dots, so it may have originally been a cheapo model. It has been in my family in the late 1970's in a state of semi-repair. I just got my hooks on it, and am finally going to get it restored (bracing glued back on, and trim replaced.) I am not planning on having it repainted, unless it is absolutely necessary in order to protect it. The scratches and bare spots tell the story of my childhood, living in a school bus with 4 siblings and my parents.
