The scope and mount on this rifle raise a question for which I have never had a satisfactory answer. When a scope such as this, which has no internal windage adjustment, is sighted in, using the rear mount to provide windage, how does the front mount deal with the torque? Is there some unseen mechanism which allows the scope to subtly pivot, or is the scope simply bent?

There are several obsolete American made mounts, some dating from the '30's, which provide for windage adjustment (Griffin & Howe and Noske come to mind, as well as Redfield, Sisk, and Buehler), but they all allow the front ring to pivot, avoiding putting any stress on the scope tube. I can see no such mechanism at work here.
