Right, I got the violin and music sheets from vault 92 and gave the violin to Agatha. After checking my inventory for some reason the music sheets weren't there so in my frustration I shot her. This means I can't gt the Blackhawk now. It happened some time ago so I don't really want to go back to an earlier save. Anyone know a way I can get Blackhawk? A console command, perhaps? Thanks.

If nothing else works, the console command is player.additem 303a2 1

Awesome thanks. All the sites that would tell me are blocked at work
