Equivalent locally finite form of Kuhn's unbounded strong realization conjecture

Let MM be an unstable module. For each integer ss, let RsM\mathrm{R}_sM denote the reduced quotient associated with the ssth stage of the nilpotent filtration, and call an unstable module of finite weight when its weight is finite. Say that MM is topologically realizable when it is isomorphic to the cohomology of a topological space.

Locally finite form of the unbounded strong realization conjecture. If RsM\mathrm{R}_sM is of finite weight for each ss and MM is topologically realizable, then MM is locally finite.

The source presents this as another form of the unbounded strong realization conjecture, using the preceding lemma relating membership in the Krull filtration to the modules RsM\mathrm{R}_sM. No resolution is stated in the supplied text.
