seller note I consider the Dentaphone, if not the Holy Grail of hearing aids, then certainly a piece of the True Cross--realizing that neither of these is usually found mint and boxed with instructions
comment Very rare item in pristine condition and with its box. I have one, WMU has one, I understand Phisick has one. The Hearing Aid Museum has TWO!

Deaf 3rd Reich has one - any more ?

The little pin is to secure the cord when the plates are bent in use. The hinges are good as new. I have the original instruction sheets too
