I'm not sure how useful this will be for you, but http://vx.netlux.org/ has a decent collection that's somewhat dated.

Thats actually where I got the current three from, went for the rather large bittorrent option. I've tried testing a lot of the worms from that collection, a lot of them don't seem to replicate under WinXP (with no service packs), I think, as you say, due to their age.

I did some searching and came across a section on malwarebytes.org: http://www.malwarebytes.org/forums/index.php?showtopic=23225

Sorry, I couldn't be much help. Good Luck.

Thanks, that looks another useful site.
