III  UPRIGHT DROP ACTION
SPINET

 

Gray shaded areas are felt parts.

This "drop action" design is more precise and easier to service
than the wire and elbow arrangement below.
This action is found on Baldwins and a few other pianos.

 

HERE IS THE MOST COMMON "DROP ACTION"
WITH THE WIRE AND ELBOW ARRANGEMENT.

The table below is the same as the Upright Action elsewhere,
so don't be bothered if you notice a few numbers
which do not appear on the above diagrams.
