I've got a book on old radar systems written before WWII.  In this book it
discusses vacuum gap tubes.  It has a list of tube numbers, ratings,
designs, life expectancies for these spark gap tubes.  I have been looking
for years for these beasts, but never found one.  I am going to dig the
book out later tonight, and get more info.
