The only thing I can think of as a source of this information is
the atlas der buurtwegen / atlas des chemins vicinaux.  At least
it should cover all old borders, and is probably want we want to
use to mark the old borders.

The question is about under what license those are available.
It's my understanding that copyright for the original maps
has expired.  I guess the same applies to scanned versions
of those.  But I would guess that the georeferenced versions
do have a copyright, or could at least be problematic.

Assuming we can use the old cards, it has all the parcels
on them.  They could help in trying to find the border based
on pictures of them, but this doesn't always seem to be easy
to do.  But as far as I know, this is currently the only
available way to do it without license problems.
