I am a collector of Mandrake Linux versions, I am currently missing:

Mandrake 5.1 "Venice" (Came on 1 CD) (I don't truly need this one, but my site could use it for completeness)
Mandrake 5.2 "Leeloo" (Came on 1 CD)
Mandrake 5.3 "Festen" (Came on 1 CD)
Mandrake 6.0 "Venus" (Came on 1 CD)
Mandrake 6.1 "Helios" (Came on 1 CD)
Mandrake 7.1 "Helium" (Came on 2 CDs)

The reason: A website about vintage and modern Linux versions including screenshots and downloads!

EDIT 5/20/2006: Found "Air" (Thanks to Xolo)
EDIT 5/27/2006: My Copy of Helium corrupted itself with age, I need another copy, both CDs

I believe I have Air here, it's one CD I once labeled as 'Linux Mandrake 7.0-2 (Air) For i486' which i've used once or twice just to see what it's like.
If that's the exact version you're looking for I could make it available. Have to note though the contents of the CD might not be 100% error free, I didn't have such a reliable Internet connection at the time and md5sum was something I had never heard about..

You can put the image up on the net somewhere, just let me know where
Thanks in advance!

PS I prefer ISOs, but you can post a raw install tree, I can make the CD (I only need the Mandrake and Images directories)

Took a while, but here it is: http://firefox.kennemercollege.nl/archive/mandrake/
I had to find another disc because my first one seems to be corrupting itself with old age.
Also please excuse the 50~Kbyte/s transfer rate, my boss is rather cheap.
