We study a previously developed composite model for quarks, leptons, and weak bosons without broken gauge interactions. The conjectured pattern of symmetry breaking is discussed, paying special attention to the 't Hooft anomaly conservation requirement, which is fulfilled. Using techniques similar to those earlier used by Hung and Sakurai, we study the neutral-current structure and gauge-boson masses in an effective left-right-symmetric Lagrangian. Under some hypotheses, we find $m_W\le 127$ GeV for ${{sin}^2\theta }_W\simeq 0.22$ and $m_Z\le \sqrt{2}{m}_W$.
