Help us to identify these objects. Some of our donations are so unusual that we have no idea of their identity, purpose or operation. Maybe you are familiar with some of the objects or can tell us, from their description, how they work

A MEDICAL INSTRUMENT?

The object is about 1 foot (30 cms) long. The tube has space for a number of batteries and has a mechanism at the 'spatula' end presumably for stimulating the spatula in some way.

It looks like the object has a medical purpose, but exactly what?
