I'm trying to understand how escapement occurs with this wippen. It appears that the top of the rep lever hits the drop screw, pushing the rep lever down, which in turn trips the jack with the letoff button on the spoon (attached to the jack) - is that correct?


Interesting for sure.  Where were Schroter's made?  Thanks for sharing.

    Found this action in a 1920s Schroter piano, a      make I've not encountered before, piano or action.  How      undulating!
