This work is intended to estabilish the equivalence between gauge and non-gauge abelian models. Following a technique proposed by Harada and Tsutsui, it is shown that the Proca and chiral Schwinger models may be equivalent to correspondent gauge invariant ones. Finally, it is shown that a gauge invariant version of the chiral Schwinger model, after integrated out the fermions, can be identified with the 2-D Stueckelberg model without the gauge fixing term.
