Comment #45 on issue 2823 by [email protected]: Patch: Fixes position of mensural c clef
http://code.google.com/p/lilypond/issues/detail?id=2823
I looked through my facsimiles at home, but they are almost useless since generally they are photocopies of microfilms, so fine details (extra strokes, slants, etc.) are indistinguishable from noise.
I'll get a book tomorrow night about the Alamire manuscripts; I think it has a study about the glyphs used and I hope I can get some high quality scans.
