We investigate the pattern of CP violation in \Kd, \Bd and \Bs mixing in a symmetrical \model model with spontaneous CP violation. Performing a careful analysis of all relevant restrictions on the model's parameters from ΔMK, ΔMBd, ΔMBs, εK, the sign of \ee and the mixing-induced CP asymmetry in \goldd, we find that the mass of the right-handed charged gauge-boson, M2, is restricted to be in the range 2.75 to 13 TeV, and that the mass of the flavour-changing neutral-Higgs bosons, MH, must be between 10.2 to 14.6 TeV. We also find that the model, although still compatible with present experimental data, cannot accomodate the SM prediction of large CP violation in \goldd, but, on the other hand, predicts a large CP-asymmetry of \cal O(40%) in \golds. These specific predictions make it possible to submit the model to a scrupulous test at B factories and hadron colliders.
