Perof grand damper levers

[Richard Brekne]

Hi folks.

Just got done with a hammer replacement job on a Petrof 235 or so long 
grand, about 20 years old in use at the university.  I got Andre to 
acquire a set of Renner Wurzens in the original design, a bit softer 
pressed then they come stock.  After the usual string leveling and 
hammer mating, regulation etc.. they sounded just wonderful.  About 35 
stitches in each shoulder in the bass and middle, a little less in the 
top. They sound simply dynamite. And you can almost feel the resiliency 
in your shoulder blades as you play. Really quite the sensation.  We'll 
do a recording on it soon and I will post it.

But the reason I am writing is that I noticed that the damper levers 
have swiveled wire holders for the damper wire.  Havent run into this 
before, tho no doubt its not so unusual.  The wires enter a small block 
with screw as usual, but that block is center pinned to the rest of the 
lever so it can swivel sideways, presumably to allow for less wire 
bending regulation.

Was wondering if any of you have any experience with these, and what 
your thoughts are.

Cheers
