Re: The Whistler
Most of the ones that have been "discovered" are from the USAFE recordings that were home recordings done by a service person or a family member while assigned for the military or civilian support in Europe. These are the 32 USAFE Whistler episodes in the collection... and it includes some missing episodes or versions. My sense is many of these fell out of circulation because the sound was so bad at that time. This is a list of the "new" ones.
