You need to fetch the git notes, then you can grep them for the SVN rev 
you're looking for.

$ git fetch origin "refs/notes/*:refs/notes/*" && git fetch
$ git checkout `git log --format=%h --notes --grep='revision=367627$' main`

It's git commit 9aa6d792b549 for reference.

Note, the `g` in there is by design, it's the format that git-describe 
will barf out.
