And maybe the bridge pins just weren't filed down quite far enough. What is
the spec for bridge pin height, anyway? :)

I have seen several Steinway pianos with the bottom of the strut filed at
the point where it crosses the bridge (and also at the curved area inside
the "cut out" for the bass end of the bass bridge) to prevent rubbing. Was
that "planned"?
