Query: Constraints on Extra Gauge Bosons in e gamma Collisions   We investigate the sensitivity of e- gamma ---> nu_e nu_mu(bar) mu- to extra
charged gauge bosons. The sensitivity is much below that of e-e+ ---> nu
nu(bar) gamma. We conclude that e- gamma ---> d u(bar) nu_e and e- gamma ---> f
f(bar) e- are also inferior to e+e- collisions in setting bounds on extra
charged and neutral gauge bosons and on four fermion contact interactions.
