OK, so I've done some work, the bow has been taken to 16" on a long string hanging 1" and is starting to show a small amount of strain (1/4" of set). The outer third of the left limb contains 6 knots and is naturally r/d . I think the centre of the right limb needs to come around a little bit , and the outer 1/3" of both limbs need to come around as well, but my eyes are starting to hurt.
