Reviewing a path-integral procedure of recovering gauge invariance from anomalous effective actions developed by Harada and Tsutsui in the 80's, it is shown that there is another way to achieve gauge symmetry, besides the one presented by the authors, which may be anomaly-free, preserving current conservation. It is also shown that the generalization of Harada-Tsutsui technique to other models which are not anomalous but do not exhibit gauge invariance allows the identification of the gauge invariant formulation of the Proca model with the Stueckelberg model, leading to the interpretation of the gauge invariant mapping as a generalization of the Stueckelberg mechanism.
