Previous work by Novello and Neto has been done with the linearized Lanczos potential as a model of a spin-2 field, which depends on a massless limit of the field. In this paper, we look at an action based on a massless potential, and show that it is classically equivalent to the linearized regime of general relativity, without reference to a massless limit.5 pages, LaTeX 2eGeneral Relativity and Quantum CosmologyHigh Energy Physics - Theorytext
