It has come to my attention that the "Town Plan" map from 1944-1967
in NLS is available freely.
What are its licensing terms?
"available freely" does not mean "compatible with OSM license"
It's out of copyright, so there aren't any licensing issues in deriving
data from it.
I would, though, be a little reluctant to use it as a basis for
wholesale numbering without any supporting local knowledge or survey.
House numbers can, and sometimes do, change, particularly when streets
are renamed or rebuilt. So you can't be 100% certain that a house number
in the 1950s is the same number it is now, even if the building is still
the same.
