Why confusing? Because the gravities are all over the shop. I think what we a re looking at is more than one brand.
Before 1931 none of the beers is a version of their draught Stout because the OG's are all too low. After 1931, the ones hovering around 1040 could well be as, if you remember from the last part, that was about the OG of draught Stout.
Judging by its (low) gravity, Oatmeal Stout was definitely a different beer from the others. Not just the standard Stout with a token amount of oats in it packaged up differently. That was the case at both Whitbread and Barclay Perkins.
There's one feature all of these beers share: a relatively low degree of attenuation. In the case of the last Oatmeal Stout, very low. How ironic that Family Stout is the only one over 4% ABV.
