  We present a SU(2)_L * SU(2)_R * U(1) left-right symmetric model for
elementary particles and their connection with the fermion mass spectrum. New
mirror fermions and a minimal set of Higgs particles are proposed. The model
can accommodate a consistent pattern for charged and neutral fermion masses as
well as neutrino oscillations. The connection between the left and right
sectors can be done by the neutral vector gauge boson Z and a new heavy Z'.
