We compare distributions of leptons produced in hadronic collisions, by a horizontal neutral gauge boson, Z' suggested by the Sp(6)L ⊗ U(1)Ymodel, to those produced by other theoretically motivated neutral gauge bosons occurring in left--right symmetric models and in superstring-inspired E6 models. Forward--backward asymmetries in the gauge boson leptonic decay are found to be sensitive to specific forms of the couplings. The asymmetries are expected to be maximal for Z', distinguishing it from the other Z's.
