Comment #37 on issue 2823 by [email protected]: Patch: Fixes position of mensural c clef
http://code.google.com/p/lilypond/issues/detail?id=2823
I'll look through the c-clefs I have; my preconception is that there's no great need of distinction based on which line they sit, so any Petrucci c-clef (with excess strokes stripped) would suit me perfectly.
