Just finished my latest refurb. A Ralph Lauren pewter brush from their Safari line (back in the dim past). Got some great advice from a couple of members. Put in a 22mm knot from TGN (Finest) set at about 50 mm loft. I'll give it a night to solidify. I'll try it out for tomorrow's shave. The brush handle was in really great shape (like new) so getting polished up was a breeze but removing the old knot required patience and a new Forstner bit in my drill press. This will fit nicely into the rotation with my other brushes; my first brush ever 56 years ago - Ever-Ready #750 with TGN Premium 20mm knot, my Simpsons Duke 3 in Best Badger, and my Yaqi 26 mm 2 band badger Moka Express (what a beast of a brush!).
