I think a part number from a lock itself (which I'm guessing would be visible on the outside of the lock) would be helpful, or if someone has some of these locks with keys that they aren't using, I would definitely be interested in buying them.
I'm guessing lots of users have harvested these boards for the Nixdorf Blacks and probably wouldn't have a use for the locks, or at least might have a lock to find a part number on it so I can do some googling
