There is evidence from recent experimental data that the {τ} lifetime is longer, and B⁰-B{} ⁰ mixing greater, than was expected in the standard model. We note that a gauge model of generation nonuniversality proposed in 1981 predicted both of these results. We study in this paper the gauge and Higgs bosons of this model and discuss some of their properties. An approximate global-SU(2) symmetry is identified and a likely scenario is presented in which two triplets and two singlets of Higgs bosons have masses significantly below 100 GeV and should be accessible to experimental discovery in the near future.
