Very nice article. However, one photo refers to a "screw grip". I don't believe the Model 700 is a screw grip gun, unless maybe very early ones were made that way and the design later modified. A true screw grip (like the Models 400 and 500) requires a 3rd fastener in the form of a top rib extension that fits into a slot in the face of the standing breech. When you look into that slot, you can see the threads on the screw which the rib extension engages. My Model 400 Grade 1 is an example.
It also has disc set strikers.
