Using our previous bounds on [Delta][rho] and the [ital Z]-[ital Z][prime] mixing angle [xi][sub [ital N]] in the SU(2)[sub [ital L]][direct product]SU(2)[sub [ital R]][direct product]U(1)[sub ([ital B][minus][ital L])] model from the [ital Z] line shape and energy-dependent forward-backward asymmetries of the 1990 data from CERN LEP, we obtain a strong lower bound [congruent]439 GeV at 90% C.L. on the right-handed charged gauge boson mass for [ital m][sub [ital t]]=200 GeV using commonly chosen Higgs triplets, which becomes stronger for doublet Higgs fields. It is independent of the neutrino mass or of assumptions about the right-handed quark mixing matrix. Consequences of more exotic Higgs multiplets are also discussed.
