All Holton French horns, including the single and double models, feature valve rotors that are tapered. This is so that as the valve wears, it automatically seats itself. This includes the bearing surfaces axles on each end of the valve and the bearing plates. All of their bells are made with overlapped seams. This is much more durable than one made with a butt seam. It also produces a better tone and timbre. This is one of the outstanding characteristics on which Holton French horns developed their reputation. They feature four different sizes of bell throats, small, medium, large, and extra large. All are hand hammered with slightly varying diameters.
