We point out that the nonlinear sigma models on symmetric spaces as considered by Eichenherr and Forger can be generalized to include a larger class of models possessing dual symmetry. The well-known axially symmetric gravitational vacuum and electrovac problems as well as the axially symmetric Kaluza-Klein dyons fall into this class.
