Maybe someone was trying to keep the mice out with that screen wire stuffed in there. LOL!
It looks like one of the pins has already been replaced by a bolt, or maybe a nut was stuck under the head of the pin.
The twist in the bar that goes into the door is normal, so don't try to straighten that.
What I did with mine was remove the pins and drill the bar hole a bit larger to take oversize pins with bronze bushings. See pic.
And I replaced the hold-open springs with repop ones I got from Jim Carter.
Good luck on restoring them. There are a couple tech tips on rebuilding door hinges.
