Using deformation theory based on BRST cohomology, a supergravity model is constructed which interpolates through a continuous deformation parameter between new minimal supergravity with an extra U(1) gauge multiplet and standard supergravity with local R-symmetry in a formulation with a nonstandard set of auxiliary fields. The deformation implements an electromagnetic duality relating the extra U(1) to the R-symmetry. A consistent representative of the R-anomaly in the model is proposed too.
