Joe,

I don't know how many modern era bows have this geometry, but it isn';t many. Back in the 70's and early 80's this used to be the norm. The deepest part of the grip was the physical center of the bow. The shelf and rest was always mounted higher than center. How much I don't know, but probably about 1 1/2" or more.

Not having been as educated back then I would only assume this is one reason we set our bows up with uneven tiller. Usually the bottom limb was about 1/4" shorter in tiller measurement.

I do remember one thing about them though. They balanced better, both on my belt hook and at full draw. And they aimed better, too, without being top heavy. And shot just as well I might add. Just a tad slower.
