Besides the cracked aged peeling paint, the doors have another common feature that tells us a lot more. The locks are constantly being updated in the history of the people behind it, being protected from intrusion.
One can see patterns of repair and replacement that shows the work aounds for the wooden haviung deriorated in the original locations so that the lock was no longer secure and thus a new spot was created.
Here in the USA, one would simply junk the door.
