Just found this fusion rifle relic farming draksis that is asking me to talk to banshee-44. I haven't seen anything about this so I was wondering. Also I'm pretty sure the RAS stands for Rasputin.
EDIT: sorry guys got ahead of myself and thought I'd found something amazing.

That's what seems most likely. There are a few other things directly tied to Rasputin there as well. I've turned four in but haven't advanced the quest yet. Good gunsmith rep though.
