I recently acquired eight Ludwig & Ludwig drum washers. I think they are very cool and should clean up nicely. The seller said they were from the thirties to forties. They are stamped Ludwig & Ludwig, Chicago, U.S.A. Each washer is 7/8 inch in diameter with a 1/4 inch hole. Although they appear to be too small for vintage cymbal stand washers (although they do fit the shaft of my 1400 stands), I was wondering if they might have been used for helping to secure the pads to vintage foot pedal beaters. Any help would be appreciated. Thanks!
