Very nice Cecil. In the 3rd picture showing the trigger plate, the two mis-aligned screws have likely been re-installed on the wrong side. There is a definite left and right screw. If you are comfortable removing them and re-installing, they will likely stop with the screw slot in line with the long axis of the gun.
DON'T JUST USE ANY OLD SCREWDRIVER. The only screw drivers to touch such a gun are hollow ground tips that completely fill the slot (width, length and depth).
You don't want to damage the screw heads.
Also, if you are comfortable with taking off the forestock and removing the barrels, there can be interesting information stamped into the barrel flats and the frame.
A picture of the muzzle end of the top rib may give a bit more info.
