First of all, here is the saddle. You can see where I already cleaned.
Issue #1: One of the nails sticks out, and keeps the concho from "laying flat". Can I just pound/hammer it back in?
Issue #2: This part/nail/tack (what's the name, anyways?) is loose. Can I just hammer (lightly, of course) that in as well?
Issue #3: Silver. All of the silver on this saddle (conchos, tips and the piece in the picture) is tarnished/chipping off. Where can I buy some new silver? Doesn't have to be super high quality, as long as it doesn't rust/tarnish easily.
Issue #4: Right stirrup. I know I can't fix this myself, but I'm just wondering if it's still safe to ride in it? It's only one stirrup, and it's only at the top.
Issue #5: Left stirrup. I can probably get a cobbler to replace the tread cover, but is it even worth it or should I just get a new pair of stirrups?
Issue #6: Latigo and off billet. The saddle came with an old, ratty nylon latigo and off billet. I'm looking to replace both of those. Should I go with nylon or leather? Any brand/length I should look for or avoid?
I think that's it, for now at least. Any help would be greatly appreciated!
