Baldwin accujust hitch pins

[Farrell]

Hmmmm. I don't know - that would be news to me. Maybe adjustable to some
degree upon installation, but pretty hard to adjust afterwards. They are a
pin that is pounded into the plate, so I guess while stringing the piano you
could indeed install some a bit higher or lower than others (a one-way/time
adjustment). So perhaps you are right - they can be adjusted, but less so
than a plain vertical hitch pin.

The Walter pins look real pretty also.
