We construct an explicit topological model (similar to the topologicalSpringer fibers appearing in work of Khovanov and Russell) for every two-rowSpringer fiber associated with the even orthogonal group and prove that therespective topological model is homeomorphic to its corresponding Springerfiber. This confirms a conjecture by Ehrig and Stroppel concerning the topologyof the equal-row Springer fiber for the even orthogonal group. Moreover, weshow that every two-row Springer fiber for the symplectic group is homeomorphic(even isomorphic as an algebraic variety) to a connected component of a certaintwo-row Springer fiber for the even orthogonal group.
