I'm afraid I couldn't find the pictures of the brush when I received it originally it was pretty beat up. I ripped out the old knot. Technically it was mostly falling out. and put in a magarrds Silvertip 22mm. I like it. Works pretty well.
There is a penny and a dime inside to lift it up a bit and some epoxy (gflex). It is an Eveready 3041
