I have to ask, did you reflex the whole limb on that bow. I ask because I noticed the caul to the right. It looks like a form for just reflexing the whole limb.
My bow is on it in the picture and you are exactly right, the entire length has a backset to it. You can also see the heat gun (blue) on the ground in the pic.
Below is a wonderful pic of me working it, had a real nice character knot to deal with.

No time to remove face makeup from the morning hunt.
