I've been collecting vintage MIJ snare drums for years now! The majority of those in my collection have unique features, such as the finish, hardware or both.
I've had this "Karen" labeled snare drum for a few years now and finally did a complete disassembly, cleaning and detail. All original parts, except for the drum heads, including Gretsch-style lugs, Slingerland-style Clam Shell strainer, blue glass glitter wrap and die-cast hoops with a cool profile I've never seen before. The drum actually sounds good!
