From memory - so therefore probably very wrong:
NATO common Approach: 362.3 122.1
NATO common Tower: 257.8 122.1
NATO common Director: 344.0 123.3
NATO common Talkdown: 285.4 123.3
NATO common Fixer: 317.7 ????
I also remember the 142.29 mentioned above on the very old 10 channel VHF ATC standby boxes; the only time I saw it slated for use was in conjunction with some post-apocalyptic Civil Defence/ROC exercise. Needless to say it didn't do what it said on the tin! I think 117.9 may have also been on those antideluvian VHF boxes too, labelled simply 'Common'.
