I finally made my way back to the 1922 Ludwig grand that contained the Staib- Abendschien action, this time with camera in hand. The instrument is in generally poor condition but tunable and playable. I guess the photos will show the simple concept of this action. It is not nearly as complex as the previously shown vertical “Mastertouch” action by the same maker. - Mark Ritchie
The action frame is screwed to the keybed. Soft pedal function raises hammer rail.
The basic wippen. Note the coil spring on the jack, and leaf spring attached to hammer butt.
