I wanted to add that I did encounter this on a Steinway a few years back. I had already redone the plate and didn't discover the problem until I was pretty much done stringing. There was a small sand pocket in front of one of the treble pins and the pin and, of course, it started to gradually lean forward. What I ended up doing was drilling out the sand pocket (it was fairly small) and epoxying into place another metal pin which was cut to length so that the top level was just below the surface of the plate. The original pin was replaced just behind it in its original hole so that it butted up against the front filler pin. I used a high density epoxy filler and leveled it off over the repair pin. Sanded it carefully in as small an area as I could and then touched up the plate. So far so good and the repair is not really visible except on very close inspection.
