What's the story on this? In some drawings, like this picture which of course is from the T. Downs drawing, there is a part approaching the neck pocket that goes from concave to convex (and maybe concave again very subtly at the top). But I don't see it in other drawings (for example ones from fmicassets), where is just stays concave until thinning out at the neck pocket. Are there different shapes in different periods? I'm currently making a plywood template, and I'm wondering how to finish this part.
