1960s Kent blue sparkle. When I got this on ebay it still had the original throw-off and snare side head and the wires that came with it were in pretty rough shape. I replaced both heads, put on new snappy snares and a Dunnett throw-off and had the bearing edges recut to dual 45s. (They were previously rounded and in rough shape.) Below are audio samples of before and after. listen - original  listen - with new snare wires, strainer, edges and heads
