Interpretation of the U(1) generator of the left-right--symmetric electroweak model in terms of B-L enables us to study the spontaneous breaking of local B-L symmetry. The same Higgs mechanism at the ''partial unification'' level of SU(2)/sub L/ x SU(2)/sub R/ x SU(4') that produces ..delta../sub L/=2 processes (e.g. Majorana neutrinos) also yields ..delta..B=2 processes (e.g. ''neutron oscillations''). The observation of ''neutrinoless'' double ..beta.. decay and ..delta..B=2 nucleon transitions without proton decay would favor this model and an intermediate mass scale.
