For what it's worth, your pictures show a common failure in that construction of relays. the dissimilar metals have dissimilar expansion rates and if the relay is subjected to heating/cooling cycles the problem will speed up. The expansion/contraction loosens the rivet which holds the thing together, a minor amount of corrosion appears, and you have a small but powerful electric heater. Note in the second picture, the actual contacts don't look bad, what can be seen of them, but the riveted connection has gone Dixie in a rathjer smelly fashion.
Smell often points up a problem before it's visible.
