/Steinway B

My guess at to why the felt is wearing on one side is the side-bearing
induced at the factory and perhaps a rough, oxidized wire.

Clean and polish the wire and adjust the bends so that the wire travels
straight in the bushing and not bearing on a side.

Once the wire travels without friction, in the bushing and in the top flange;
adjust the head over the center of the unison and check its proximity to
the plate. You may end up trimming some of the head.  Make certain
that the 90 degree wire bend above the strings is at a suitable angle.
