Hi, I am interested in identifying the year of this snare as it is currently missing the external damper knob. I have the damper mechanism and would like to repair it with one from a similar vintage if at all possible as the snare is in otherwise as new condition. It is a 14x6" 6 lug Pearl Snare Made In Japan. I have included a montage below showing the badge, finish and all hardware. Any help that can be provided would be greatly appreciated.
cheers
