I am trying to find a recommendation for a straight boar knot. This will be to restore a very old shaving brush, the depth of the brush allows approx 9mm(8.98mm) and the throat of the ferrule is 17.35mm, making me think a 16mm would work. Also, I would like to limit the loft to 48mm, but 46mm-48mm is the target. From what I can tell, based on my little brushes, it would need to basically be the knot in the little Rubberset/Gillette Travel Brushes. The Wee Scot might work, but I can't tell. The ER 200CC are too big and likely require too deep of a seating. I am waiting to post a picture of the handle until I can do a before and after at the same time.
