Also, being a merge commit, it's rather impossible to even infer which commit this might have been near. Personally, I like to take my series', tag them, then throw them out in a public git tree somewhere. That has two advantages. First, it makes it easy for a reviewer to look at the series as a whole in its applied state. Second, it makes it utterly trivial to figure out where the series was based because the entire history is there. The entire history will be there even if you based it off some tip branch that got rebased away since.
