Hey Gretsch people! I have had this snare for a few years, and I don't know what model it is. It is full of issues and missing parts, most notably the model number and badge, but functions. No vent grommet (if there was one), no key holder, non-matching lug casing screws and washers, pitting on throw-off and hoops... I'm also not sure if the adjustable butt plate is correct, but I don't see any extra holes inside. I've surfed around and haven't found this drum. Any help is greatly appreciated. Thanks in advance!
