The year was 1973 when this (probably one of the most famous) Russian series was filmed. To all of us fascinated by number stations, I would consider this to be one of the mandatory films in collection!
It is definitely worth watching the whole episode (and the whole series on that account) to get the feeling of how the life of those, receiveing the number stations broadcasts for living, look like.
For those eager to fast-forward, you can go directly to a 1:01:00 towards the end to see, why this video is relevant here. But whatever you do, do not skip the end title music!
The whole show was recently restored and colored to a very good quality, but this one is having an English subtitles and is a whole first episode, so I will link this for now.
Don' t know how long it will stay in YouTube like this (its not my upload, so there is not much I can do), but please enjoy it meanwhile!
