We reexamine the {ital K}{sup 0}-{ital {bar K}} {sup 0} system in the SU(2){sub {ital L}}{times}SU(2){sub {ital R}}{times}U(1) model of {ital CP} violation with three generations with special emphasis on the minimal model of spontaneous {ital CP} violation. We give a new estimation of the hadronic matrix elements entering in {epsilon}{prime}/{epsilon}, taking into account constraints from current algebra, final-state interactions, and short-distance QCD corrections. We compute, for an arbitrary number of generations, the phenomenological {ital CP} phases in terms of the quark masses, the parameter {ital r} (ratio of Higgs vacuum expectation values), and the single {ital CP} phase {alpha} of the model. We make a three-generation phenomenological analysis taking into account the high multiplicity of the sheets for the {ital CP} phases and the uncertainties in the Kobayashi-Maskawa matrix elements and {ital m}{sub {ital t}}. For low {ital M}{sub {ital W}{ital R}} the two-generation {ital LR} part dominates for most of the solutions, but the pure {ital L} three-generation contribution can be dominant in some cases.
