Vintage scope question

[LesPaui+sg=win]

We rigged a mount for a .50 cal that we were shooting single rounds out of. We had a few shots and then it was all foggy, apparently we separated the lenses...OOPs...



Perhaps it's would all the way one way and is jammed. It shouldn't need small screws loosened I shouldn't think...

The reticle looks 100% centered when looking through the scope. Doesn't the whole reticle move when adjusted? That's what makes me wonder if the dial was maxed out and jammed in one place. I know its impossible to tell for sure unless the scope is in hand. Were any of these scopes made and calibrated to one specific rifle/load? As in, were any of these made to be unadjusted? Just windage adjustable via the rear base/mount? This has what looks like the original claw mounts, the rear is windage adjustable.
