Right after receiving it back the latch was extremely stiff, but with use has loosened up since. I have not fired it yet, but everything seems to function correctly when pulling the trigger.
It's just the squeezer itself stuck and not moving one way or the other. When i get home tonight I will remove the stocks and get a little Rem Oil or penetrating oil in the general area, to see if I can free things up. I've had great luck with Walmart brand penetrating oil (don't laugh) on the internals of not just my Smith top breaks, but also my Ivers, etc. In fact, it's become standard practice when I make a new acquisition. You never know what kind of gunk is up there after 100 plus years.
