Another term for this design is "sticker" piano, as it has very long stickers reaching from the tops of the jacks to the hammers. The jacks are attached to the keys, and escape from the bottoms of the stickers.
Tuning a piano like this requires a long stretch, to reach the key and the tuning pin at the same time. The piano was provided with a shift pedal to move the hammers relative to the strings so that only one string would be struck.
This piano is of entirely wooden construction, and has neither metal bracing, nor an iron hitchpin plate.
The tuning pins are all marked with note names.
