Dule, nice find! These COS snares were made in the late 60s through the mid 70s. Tis is one of my favorite all time snares. Clean it up, use the Taiwanese snare wires if you have to change them and coated Ambassador batter and hazy reso or bottom side heads. If you use Bob Gatzen's tuning method, found on youtube, you will get it right in the sweet spot. I like as well as any other snare, including the Supra. It is one of Pearl's best snares they ever made. And it was never really supposed to be anything more than an entry level drum. They just did this one right.

Tis also may be a brass snare. Do a magnet test on the shell. I have seen many of these snares, some of them seem to be COB. With 10 lugs, this may be one of the greatest players out there, bar none.

Congratulations on another great find! They run in the $30-50USD range mostly in the States. And bonus, yours has a Pearl badge, most of these have a stencil name badge on them.

Can't wait to hear the result of the magnet test. I am not sure they manufactured COBs at that badge period- but if it is, I agree with you that is would be a real findWalking NICE one!
