I have seen none of those variants. The last one you show has a lot of visuals, a rope (cord) and tassel, a lyre, the ribbon band, and laurel leaves without berries.
What are the two cities wappen other than Nurnberg? They look familiar.
( I'm guessing the blue shield with the gold or yellow eagle could represent the (eagle with the king's head) of the greater Wappen of Nurnberg. The half-eagle shield with red and white bars being the lesser wappen of the city).
Got it, the half-red and three white (peaks).
Franconia. Thanks for showing them, Don.
