  In this work we consider a left-right model containing mirror fermions with
gauge group SU(3)$_{C} \otimes SU(2)_{L} \otimes SU(2)_{R} \otimes
U(1)_{Y^\prime}$. The model has several free parameters which here we have
calculated by using the recent values for the squared-neutrino mass
differences. Lower bound for the mirror vacuum expectation value helped us to
obtain crude estimations for some of these parameters. Also we estimate the
order of magnitude of the masses of the standard and mirror neutrinos.
