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.
