If you go to most any AD they will sell you spare spring bars, I buy mine locally for $12/pair. Most aftermarket I've bought suck, they are nowhere near as strong as the gen -they bend easy and the springs give out in no time.
I dig the fat font insert on #2 but yes if that is genuine patina on the dial it's likely from high humidity and the guts will need close inspection. And finding a more aged insert is easy.
If you're not a fan of the sword hands why do a 5517? The sword hands (and 60 min bezel) are the distinguishing hallmarks of the 5517 vs. a 5513.
