Thanks Yoshi, you just made my day! I had my suspicions that it was COB, and I've been wanting a brass shelled Ludwig snare for an long time, and you just helped me confirm that this is exactly what I have! That tiny little 'B' stamp was hiding exactly where your picture showed it. Here's a picture of mine. Thanks again for helping me confirm this!
You're welcome, bro!
And congrats Cool1
