Saw a different grand action than I am used to. Instead of a true unacorda, the soft pedal moved the hammers closer to the strings. What was interesting was that the soft pedal lifted both the whippens and the rebound rail. Like an upright with lost motion compensation, there was a small, additional lever on the whippen that is lifted by the soft pedal lever. The rep lever had a bossed hole for access to the rep spring screw, also. It was a something-or-other Meyer made in Chicago with ice cream cone legs. Long ago someone had glued some front rail punchings to the rebound rail felt in places for some reason. All in all it is a bit of a wreck, but will do what I can for the owners including a pin block treatment next month.
Is this a very unusual action? The only reason I noticed was that a couple of notes where blocking against the strings and I needed to pull the action. Otherwise, I try to leave well enough alone on these musty, rusty, trusty pianos. One thing I did learn is that lining up the screws when fastening the action back into the piano is not enough. You have to get it precisely where it was or the tone is different.
