The National Type B Dial was one of the first radio products made by the National Company. It was originally produced for Browning-Drake, but quickly became a mainstay for National, starting with the Regenaformer and culminating with the SW-3 Universal. Along with the National Type A Dial, it was generally known as the "Velvet Vernier" dial.
