Why do you refer to these archives as being of Maildir mailing lists?
What is the actual software that created them.

This looks vaguely like Maildir, except Maildir has no index file. What
is in the index file(s)? What is the difference between 0 and 1? Do they
each contain some complete (including all headers) messages, i.e. each
contains a set of messages that combined are all the messages, or does
one of them contain message headers and the other bodies, or does one
contain messages and the other contain metadata about the messages?

You just need to add a *nix From_ separator to the beginning of each
complete message and concatenate them.

If you can show me what's actually in some of those files, I could
possibly create a conversion script for you.

It could be as simple as something like

cat archives/0/* archives/1/* > mbox

except for the index files, but probably not.
