If the hole measures 20 mm you will need a somewhat smaller knot, such as an 18 mm or perhaps a 19 mm knot.
What I would be inclined to do would be to enlarge the hole with a Dremel drum sander and open it up enough to fit a 20 mm knot.
Knot selection is a personal choice and depends on what you like. My preference would be a silvertip badger. I have an old Erskine of about that vintage with a 20 mm Whipped Dog silvertip in it.
I'm also somewhat partial to two band finest (aka high mountain). It is nearly as soft on the face, but has considerable more backbone. That's what I shaved with this morning.
I would not consider lower levers of badger, pure, best, black, and so on.
I'm not a Boar guy but there are several here that could advise you if that is what you like.
That's a beautiful handle. Whatever knot you chose it will look great.
I'd love to make the hole bigger, however I don't have the necessary tools.. Can I just hold the brush handle by hand and drill it? Or would that require stitches? I would also need to acquire a dremel..
I had to enlarge the hole in a whipped dog handle a few weeks ago. I do not own a dremel yet but just used medium grit sandpaper wrapped around my finger. Took about an hour to go from 22mm to 23.25mm. I then smoothed it out with finish grade sandpaper.
I have that same knot that I set in a nice old Erskine handle (but not as nice as your blue Ever Ready). The F2 is a very nice knot, but it doesn't have quite the backbone of the regular TGN finest, so I'd suggest setting it at no more than 50mm loft. I'm a face latherer mostly, so I'd personally go even a little less, maybe 48mm. Of course, YMMV.Am currently sanding the hole to make the diameter 22mm. Decided to go with this knot.. Can't wait until it gets here!

Looks fantastic.
Almost done!

Going to retouch the white lettering later, but this is how it looks for now!
Can't seem to find and Flitz or Maas anywhere around here so I haven't had the chance to really polish it yet.
