So I was so excited by the Badger I just got that I was gonna going to order another (and I still will, probably from a good BST down the road). Then I remembered my display brush I ruined.
For those who don't recall I tried to boil out the knot and ended up dulling the color and removing the ink from most of the etching.
Well looking online I found a trick to hand polish a dull rubberset type brush with car wax. Grabbed some from the garage and have it a try. It didn't restore the color but it did bring shine back to the overall surface. So, with some tool and some new determination, I managed to get the knot out (not clean, but I'll work on it).
So, I ordered a 20mm mixed boar / badger to set in there (which will be closer to the original boar they used in these). Hoping I like the mixed... as I loved the badger, hated the boar. Fingers crossed!
