I recently began the process of rebuilding the Otto Higel player inside
my piano.  I am currently focusing my efforts on the bellows assembly.
I have discovered that the factory-original gaskets in the action were
blotter paper.  Where can I obtain new blotter paper to replace these
gaskets?  Or, would it be better to use a different material
altogether?  Obviously I would like the lowest-cost option, but I also
want to do the job right.
