  We examine constraints on a model with pure right-handed third generation
charged couplings. The parameters of the right-handed mixing matrix and the
right-handed coupling strength are constrained from semi-leptonic B decays, the
mass difference of neutral mesons, the CP violating observables epsilon and
epsilon', and the electric dipole moment of the neutron. We find the model to
be tightly constrained by these parameters with several fine tuning conditions
on the phases in the right-handed mixing matrix. There is also a necessarily
non-zero value of the left and right W mixing parameter. CP asymmetry phases in
neutral B decays are discussed.
