I cannot think of any red-over-white wound beads that are not Venetian.

It has been said that Bohemians made their own versions of cornaline d'Aleppo beads (these being smaller red-on-white ((or pink)) drawn beads)—but I am not convinced this is true. Or, if it is true, how one would recognize the difference(s).

I also have the nice filigrana-decorated overlay beads you show, seen here:
