Sounds good! Having never used badger I can't say as to how that would perform, but I'm sure it will look amazing! Please post a pic when you install the knot, and keep us posted!
May I please ask where you acquired the handle? It is a beauty!
I have a handle almost identical to that and the original knot looked and felt like a very well used best badger. I replaced it with an Ace Shaving silvertop knot which looks pretty good.
I like the "Spider" on the side and bottom, gives it character. I'd suggest going easy on any polishing as the Butterscotch patina may look uneven after.
I have a Culmak that has a huge knot of what looks like 2 band Best Badger, the tips are super white and soft. It's new in the box and I've never used it but I've been tempted. They made some great brushes.
Personally I would have a difficult time not using that absolutely beautiful brush, but there are people on this forum that would have some strong words for you if you did.
