I picked up this butterscotch handle a few days ago and have since removed the knot (which had been of very good quality but was looking pretty sad) and polished it up. I think it might be a Culmak brush, and was hoping somebody could confirm this, and say which model it is. The knot hole is a fraction under 25mm in diameter, and the handle stands 55mm high.
Also, I am now wondering what replacement knot to use. I'm thinking of a TGN Grade A Silvertip (would 22mm be suitable?) or Shavemac Silvertip. Which would you go for, and why?
