Thanks, Marco! I updated the thread. 

For the heraldic devices I just marked St. Christoph am Arlberg since that seemed okay in this context.
If I understood correctly, none of the Hebrew manuscripts can be assigned to anything more specific than a country. Either way, it is important to keep in mind the matter of "traveling images" in tandem with the question of the core region of the form.
