A new and simpler derivation of the equations of the "Already Unified Field Theory" of Maxwell, Einstein, and Rainich is presented. The approach is based on an extension to the manifold of general relativity of the intrinsic tensor techniques described in a previous paper.
We show that the superspace formalism follows from the component formalism. After constructing the supervielbeins and superconnections off-shell in second order formalism with the minimal set of auxiliary fields, we show that the resulting supertorsions satisfy the constraints of the various equival
