Runskrift and the German Kurrent or Laufschrift

The German Kurrentschrift (or: 'Laufschrift'!) and Sütterlin style have various letters that seem to be a clear descendants of FÀSTA's Runskrift (or: Runscript). In particular the F and the F can be convincingly related to each other, demonstrating that the Runskrift versions came first.

Much more can be said about this. This is a provisional exploration.
