I just got a hold of a Slingerland snare drum but I'm not sure which model and series it is.
It has what I assume to be a Marine Pearl finish, it' white but at the same time it has a slight tint of blue.
The Serial Number is 21930 with a bronze oval badge.
It is 5 1/2 x 14.
The shell has no markings on the inside.
I believe the throw off to be the Zoomatic.
