I was able to score some German made Cumberland Ebonite (hardrubber), in dark-brown-orange. In the past I have made many pens from this material, but now I was able to pick up some large enough for a brush. This one has a Manchurian Two-band White knot (26 mm at exit) in it, loft can be adjusted as the knot is not glued in yet (best would be 50-52 mm).Cost is $160 incl First Class shipping in CONUS. I have material for a few more brushes/handles left.
