Note: Vincent Bach used the trade names of Stradivarius, Mercedes, Mercury, Minerva, and Apollo. For some reason, Vincent jumped around a little on serial numbers. For example, in 1928 the Apollo serial numbers were 8600 - 8700. In 1939 the Mercury models had serial numbers in the 10,000s. The first Minerva (#2722) was built in 1958.
