The design with the jack being triggered by the rep lever coming into contact with the drop screw (which doubles as a let-off adjustment!) ensures simultaneous escapement. The intent of the design was to alleviate let-off resistance, however, it does not really fulfill this claim. > How do I know this???? I recently attended a convention and won a great door prize: Pfeiffer's book "The Piano Hammer".

The piano inquestion must be a Reinhold Schröter which produced up until 1930.
