I got a bunch of super cool 1950's drum sticks as part of an estate deal, and it includes these fancy-looking brass/copper/bronze brushes. Anyone recognize the brand? and/or can give me more info about the material.

Other vintage sticks I got included Ludwig S3's, Ludwig Jo Jones and Gretsch 7a's.
