Ricci flat pseudo-Riemannian 4-metrics possessing an Abelian Killing
algebra with bidimesnional null orbits are studied under the assumption that
the distribution orthogonal to the orbits is completely integrable. The
results of this paper toghether with those of part I (see DIPS-7/2004)
give a full description of Ricci flat metrics with
bidimensional null Killing orbits whose distribution orthogonal to the
orbits is completely integrable.
