I'm searching bits of informations about the exact changes between the versions of Chainmail. Those who read the ODD74 forum maybe have seen the discussion about the Blackmoor system before the publication of OD&D. But part of the problem is Blackmoor was born from the 1st published version of Chainmail, not the third - which was the  most commonly available.

I saw in the scans of Europa fanzine of april 75 that from the 2nd to the 3d edition, the number of spells in the Fantasy supplement was augmented ; that the spell complexity (level) was added ; that asian armies appears first.

So, I'd like to know, among other sthings :
- the list of spells and creatures in each version.
- In which one the spell delay table appered first?
- In which one the numbers for armor in the man-to-man range weapon table appeared first?

Thanks a lot!
