The Anchell books contain quite a few errors so read them cum grano salus.
You use a SS two reel tank with a small amount of 3% hydrogen peroxide in the bottom. An empty reel actrs as a spacer between the film and the peroxide. The film is left for a number of minutes which must be determined by trial and error for each film used. The film must be used shortly after treatment and cannot be stored as it reverts to its normal unsensitized state quickly.
If I read Anchell correct the H2O2 treadment is done after development, before fixing and not before exposure like some of the other method he covers.
