Those photos remind me to say: if you still have the original scope, don't lose it. Those early 110s are all long action guns and they require long tube scopes to mount properly and still have some room to adjust your eye relief. Problem is, no one makes long tube scopes anymore. So when you put a new scope on the rifle, it sits in one place only and if that doesn't fit your cheek position with regard to eye relief, to bad, so sad, suck it up buttercup. Because the only resolution is a picatinny base, and that's going ti partly obscure the ejection/loading port and make it harder to load the rifle.
