It really doesn't matter, though... the filter isn't much good to use.
I recently bought a lot of Nr 5 and another lot of Nr 6 filters -- about 1/3 of each lot was not good for use anymore. They are very old and it seems to take some picking-and-choosing along with a little buy-only-to-throw-out to get a good set of usable filters.
And please stop calling me "Bueller".
