Abstract
A gauge model of generation non-universality proposed in 1981 is reexamined in the light of precision electroweak measurements. Two necessary features of this model are that the tau lifetime should be longer than predicted by the standard model and that the rho parameter measured at the Z peak should have an additional negative contribution. Both trends are noticeable in the data. A future decisive test of this model would be the discovery of new W and Z bosons with nearly degenerate masses of a few TeV.Keywords
