VAN LAAR B4 BB TRUMPET S/N 3062. The Van Laar B Series trumpet are known for their sound, response, and versatility and the B4 model trumpet is no exception. The B4 was developed on the basis of the Bach Mount Vernon trumpet. Fundamental to the rich sound is a standard bell with a normal-weight valve cluster. Unlike the original instrument, the B4 is distinguished by its improved slotting and lighter intonation. This is a reliable all-around trumpet for all kinds of music-making. ML bore: 11.7 mm (0.461?). Standard weight valve casing. Bell material: yellow brass. Bell diameter: 122 mm (4.807?). Each trumpet is handcrafted in Margraten, Netherlands at the Van Laar factory. This instrument comes without a case.
