Rick,  There is a museum in New York City that archives originals of
all the old TV shows.  Off the top of my head it may be the Museum of
TV and Radio, but I am not really sure.  It is around 54th street,
between 5th and Madison Avenues.

With a little research, or possibly some input from some MMD'rs, you'll
be looking at it before long.  I know you can view shows at the museum
but I'm not sure of their sales policies.
