I have one here at the U. I service regularly. Just last night we had a
visiting Baldwin artist play a concerto on it.

Same problem, a rather heavy frictionous pedal feel. I traced it to the
pedal itself. Turns out that the bushings were way too tight. The
result: The pin actually started turning in the pedal instead. As you
would guess the steel pin began eating the soft brass. Eventually there
became sideways travel. I replaced the pin with one oversized and
corrected the bushing problem. MUCH better!
