These are our exact reproductions of the finest British bore and chamber cleaning brushes found only in the best English and European shotgun cases from the late 1800's up until WWII. The brushes are of solid brass construction with bristles available in both fine bronze wire and traditional genuine horse hair. The bore mop is 100% cotton. Absolutely no steel parts that can contact and potentially scar your expensive shotgun. Use the horse hair brush and oil mop along with our classic British pull-through kit for general cleaning in the field and use the bronze brush to make quick work of the heaviest lead fouling. Threaded to fit all of our cleaning rods as well as many of the modern rods widely available today. Absolutely the finest bore brushes available in the world today. Sold separately or as a set.
