No, it's a standard V4 body on the V4 mesh reshaped and regrouped to wear V3 clothing. It isn't the V3 mesh, so V3 morphs won't work, and it doesn't have the V3 uv mapping so textures won't work. The idea is to allow people to use their V3 clothing on their V4 characters, at least as far as textures and head shape are concerned (which was useful t some when the figure was newly released and had a limited wardrobe).
