grin... I beg to differ, but I would rather say that the instrument has need of a
fine regulation... period. Slavically adhering to one or another manufacturers
specs is in the end pointless. Fine regulation is achieved, also in the end by a
complete understanding of how the various variables intereact to result in
beautiful touch and tone. The fellow posting the query would seem to have more
need for this basic understanding then he has for a bunch of theoretically
correct numbers plomped in his lap.  Further it is not certain, due wear, ageing,
and what kind of maintainance, or lack thereof that bonehard adherence to specs
will work at all, or at least not at optimal. Indeed his question seems to point
potentially in this direction as well.

9,5 mm is 11/32 inch and 9.75 mm is 13/32 inch ( + or - next to nothing) and we
are talking L model here.

Hope you dont take offense Antares, I am not a purist, never have been and never
will be. Did you ever get a chance to see the Horowitz grand. I have had the
pleasure of viewing it and checking it out both before and after the Hamburg
people ruined it. (That ought to provoke ya... grin) They attempted to restore it
to Steinway Specs, and in the process removed any real connection this instrument
had to the personality and style of that unbelievble talent. I understand that
New York people are re-restoring it to Horowitz's preferences now. Key word
there... preferences.
