I finished redoing this a week or two ago, but only just got the stretcher made and the piece mounted. I signed it too, with both Louis Nicolas's initials and an estimated date, and my initials. I took the style of the letters from pages in the Codex that had a lot of text on them, so there is at least a vestige of Pere Nicolas's hand there.
And I am much happier with the revised version. It was definitely worth the mild tedium of picking out stitches and reworking them.
