The paper concerns vector bundles on the projective line over the ring of integers. We deal with bundles of rank 2 obtained by means of a certain base change. The source bundle runs over the bundles with the trivial generic fiber an simple jumps. We compute the minimal degree of nonvaniching sections for bundles in question. Certain interesting phenomena are found out.
