I have acquired a decent Lyman 48S 03A3 sight - but some issues as shown below - and both (I assume) that the sight be taken apart to fix. While the base and the slide do not have matching ID marks - they seem to fit together just fine! Any guidance or insight appreciated

1. the elevation clicks are MUSHY. I am sure it is just gunk - and needs cleaning.
2. The windage knob appears to have had the screw stripped out and replaced with a brass screw or rod that is not well. Again - needs disassembly to fix. How do I get that brass "thing" or of there? I have bought parts/pieces of similar sight to replace the knob (57S I think).
3. The face of the slide is considerably pitted - is that from corrosive primers and lackadaisical cleaning?
