I can't find the pip boy icon for the lever action rifle anywhere. I want to use it for a plugin, but I can't find it. It's not in game files, it's not on the internet, it's simply not there. Can someone give me a link, a file, anything?

Get FOMM (if you don't have it already) then use the BSA unpacker tool to extract it. It's probably in "PointLookout - Main.bsa"
