The Design
See my other hearing aid for some background on hearing in the twentieth century. Because this one is transistorized, I think it is from the late fifties, but I am not sure about the dating. The original battery type (see picture) is no longer available. The last generation of equipment using them were remote controls (yes, there are such things!) for hearing aids. But it can be operated from a modern hearing aid battery, which is a lot smaller, if you fill up the extra space with conducting filler.

This Object
The unit looks quite good, so do the extras that come with it (case, batteries). It works, but as I am not deaf I never use it.
