To me, there are a lot of potential variations to this profile. Here are a couple:
This is a flatbow with a narrowed handle section that works with the rest of the bow. Tim Baker says these bows 'require the highest levels of skill to tiller.' Well, thanks Tim! I don't really think it's that hard to tiller a narrowed handle so it bends. It just takes a little longer. At any rate, this is not a true 'D bow' because of the handle design--but the profile is right.

Here's a warbow I suppose you all are tired of seeing. It illustrates what Jaro calls 'eclipse' tiller. That is, a circular/compass/D profile that bends the most at the tips and least at the handle. Not exactly eliptical or circular.
