Walter 175 hammers

[Mark Dierauf]

I have been asked to voice up a set of hammers on a new Charles Walter 
175 grand. They look like Renner hammers, but are quite mellow sounding. 
Does anybody know if these are Wurzen felt? If I lacquer, should I use 
the same techniques as on Steinway hammers, or is there a better 
procedure for this type of hammer? The bass in particular needs a lot 
more oompf.
