Hello,  Jeff Mason here; I acquired a 1920 Weber Duo-Art grand piano.
It is in remarkable good condition, however the pump thumps when playing.
I dropped it from the piano and have found dry, worn bearings.

Does anyone know where or what bearings I can install?  I have learned
there are none available through piano supply houses.  There must be
some type of bearing that for some fluke of a reason will work.

Thank you in advance,
Jeff Mason
