A rare pair of solid silver ear tubes by Vibraphone dating to the
early 20th century. They come in their original blue velvet lined case
which is marked "S A Vibraphone PO Box 8948 Johannesburg". The
individual ear pieces are marked L and R respectively and "Vibraphone
made in England". They are effectively ear tubes which may have been
been of some benefit in cases of narrow external in auditory meatus
but were probably useless to the majority of users
