Viennese action

[Ed Sutton]

    Can anyone on the list inform me about replacing hammers on a late model
Viennese action?
    Some questions:
        Is it reasonable to expect to re-use the shanks, which are working
very well?
        Shall I remove them from the kapsels to remove the hammerheads, then
replace them for hanging the new hammers, or make a separate jig for holding
them while hanging the hammers?
        For a small 1870's piano, what is the likelihood that leather
covered hammers were original?  Or more likely a repair to extend the life
of worn hammers?
        Are Renner Viennese hammers the only choice?
        And what are the "Darn, why didn't I think of that first?" factors?
    Thank you.
