This is a clavichord in Lindholm's standard model.
The 8-foot bridge has been broken in six parts, later reglued, but not in the original positions. The parts are badly joined, with wood trimmed off or a new piece of wood added. The treble end (pins 133-136) is a replacement. Here the original parts have been positioned along the theoretical bridge pin line with distances between the parts according to the theory.
The bass end of the 4-foot bridge is a replacement without pins (and holes). The drawing shows a reconstruction.
The five highest 4-foot tuning pins are missing and the holes are plugged.
