Nana

According to Lostshows.com, a number of the episodes are missing. This website tracks British programs that are not complete and tries to find sources to recreate the programs in their entirety. Here is what they have to say:

"Missing or incomplete episodes for program NANA.

+ 14.09.68 The Victim (missing)

+ 21.09.68 The Queen (see below)

A copy exists which has been converted from the US NTSC system. The original 2" videotape master has been lost.

+ 28.09.68 Fall Of An Empire (see below)

A copy exists which has been converted from the US NTSC system. The original 2" videotape master has been lost.

3 episodes are missing or incomplete out of a total of 5."

It's a shame that no seems to know what happened to the missing episodes. It was an excellent production and would be nice to see it again.
