I picked up this celluloid handle in Texas a few years back. The shop I found it in was rickety, dusty, and closer to a dumpster dive than a curio shop. In fact I was on my way out of that hell hole when this handle caught my eye. It had a brittle and nasty old boar knot it but I drilled that out, filled the handle with sand/epoxy, and stuffed a 28mm tux knot in it. I have not been able to determine the maker but I love this big brush and think it looks great with the tux.
