There is a bit of further information on two of the examples from above that apparently can be found in another of the armorials from the heraldica.hypotheses <HH> list.
That source is: Weimar, Herzogin Anna Amalia Bibliothek
Search the author - Virgil Raber. He made copies of earlier armorial listings which include:
1) The tower with doors- from Marco's posting. See Raber: p 112-113 and p 496-497
2) The arched wall - from Aga's posting. See Raber: p 108-109 and p 480-481
There are some 'names' associated: Possibly 'Niderthor' with the tower and 'Weynegg' / 'Wenegg' with the wall.
There are other illustrations that also have swallowtail merlons.
1) Three gold merlons on a bend with a red background. Raber: p 422-423
2) Two blue swallowtail merlons against three white and gold? rows of square merlons. Raber: p 584-585
3) Two gold merlons on black. Raber: p 298-299 [Has no label]
