Russian 50k maps of France, any ideas how to find it?



I am a poor french man and so use altavista babelfish to read this website (!)... I am searching for days the russian maps 50k for France... I know it exists but I can't find it.
Could you help me in my search?

Thanks a lot

There are not 50000 russian maps. There are only 100000-200000 maps on this website , and many other websites. Look at this
This maps are only in russian

It is post-USSR. To find this maps is hopeless business. Because, they are secret by militarians. And all websites, devoted by maps, are carefully checking by them. Search this maps in other sites, outside post-USSR.

Thanks for your support!
Website doesn't seem to work but will try later...
