A fine and complete example of Bennett’s cased graduated ivory pleximeter and ebony percussor.
The percussor has an ebony handle with one recess for the thumb on one side and two on the other for the index and middle fingers.
The head is secured in place by means of an ivory sliver. The fitted burgundy Moroccan leather is embossed and decorated and lined with red silk and velvet. There are signs of use over the sweet spot where the percussor has struck the ivory. A similar instrument can be seen on page 163 of Elisabeth Bennion’s book Antique Medical Instruments
