Which TGN knot is it precisely, by the way? I never managed to find out, but I'd love to use it in my first attempt at brusch restoration.
TGN Finest. The knot diameter is 22mm, but the hole they're mounted in is 23-24mm if I'm reading the description right here in the original offer post. I got the Shavemac in the LE, but have restored the two brushes in my avatar with TGN Finest 24mm knots, and they are both outstanding (one's fan, one's bulb).
