Have never seen the like. I strongly suspect USA manufacture -- very keen to know more, as have been offered this pair. Each measures 22cm wide by 15cm deep. Small hole on each handset with what seems a pin for plug...perhaps for a watch receiver (extra listening device for second person during a call). No date or name marked whatsoever...which is peculiar.
Anyone au fait ? Hugely appreciate a knowledgeable reply ... many thanks !
