Here are photos of an approx 1964 6.5" Super Sensitive, badge number 3858. It is COA with COB hoops. Red 'baseball bat' muffler. The pivoting action has been reversed - to the left/counter clockwise is now snares off..to the right/clockwise is now snares on (but I don't know when this change occurred). The two sliding pieces have changed from metal to a hard nylon-type material (presumably for a smoother action.)
First photo is snares on, second photo is snares off. This drum also has the 10-strand individually adjustable snare wires.
