That doesn’t look worth fixing unfortunately. It looks like your pal was in a front end crash. If it was just bent, you could probably slip a stout bar through the bottom bracket like they did in the old days, feet either side and pull the forks forwards again. I wouldn’t risk that with the crack in the head tube.
I have tried to bodge-straighten a frame like that by pie-cutting the tubes and MIG welding them but it didn’t work well because the downtube gets compressed in the crash and you have to shorten the top tube quite a lot to match it back up. I mean, you could drill a hole at each end of the crack, vee it out, run a weld over it and see if you can pull the forks forwards enough. It’s just a question of whether it’s worth all the effort.
