Bennett’s fine, rare and complete 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 embossed and decorated burgundy Moroccan leather with red silk and velvet lining is in pristine condition. 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
