摘要：

The maximally extended Reissner-Nordstrom (RN) manifold with e (2) < m (2) begs for attaching a material source to it that would preserve the infinite chain of asymptotically flat regions and evolve through the wormhole between the RN singularities. So far, the attempts were discouraging. Here we try one more possible source-a solution found by Ruban in 1972 that is a charged generalisation of an inhomogeneous Kantowski-Sachs-type dust solution. It can be matched to the RN solution, and the matching surface must stay all the time between the two RN event horizons. However, shell crossings do not allow even half a cycle of oscillation between the maximal and the minimal size.
