Your comments:

• Could the throat microphone be used by the wearer to monitor their own speach? It becomes tricky to ensure speach is clear when hearing is poor.

• I have one of these hearing aids, set me back £1 in a car boot sale! Hivac valve line up is triode XP 1.5v followed by two screen grids type XSQ 1.5v There are no transformers, all coupling is via very leaky wax capacitors.

• Probably an early deaf aid. The "speaker" is the microphone and the box was worn so as to present the microphone to the front.
  I have not seen a throat microphone associated with such items, but it could possibly be a useful addition where people were sat side-by-side.
