I recently acquired a set of 1980s-ish Slingerland drums with serial numbers from 358xxx to 369xxx range for kick and toms. The snare does not match and as best I can tell is a much older Haskell W. Harr 10 x 14 from 1959 to 1963 (based on brass and black badge with no serial number showing Niles, Illinois).
I am specifically trying to find sources or parts (especially the threaded rod with knob end) for the internal mufflers. The only complete one is in the snare.
I would also appreciate any additional information anyone could provide about this set. Except for some heavy rust on a couple of the rims, and heavily faded wrap on the snare, It is in very good shape.
All help would be appreciated.
