The down tube needs replacement, the rear triangle looks to be pushed to one side a little, the brake bridge looks like it cracked where it is brazed to the seat stay( might only be paint flaking off). That's a lot of work. Plus, I've always heard that brass brazed tubes shouldn't be replaced. I'm assuming that's a brass brazed frame. Brass uses much higher temps than silver. Your only cost effective option is to do as exxongraftec mentioned and try to coldset (bend) it back. I doubt anybody would do the job for you so you are probably on your own. The good news is that steel doesn't mind being bent a little and tends not to fail without warning.
