I killed some Khans this playthrough and last time that have a disassembled weapons shipment that is then marked as a quest item in my inventory.... but I have never found the quest.

Anyone know?

neg,but i smoked some fiends who also guard a disassembled weapons shipment crate,think it was when i was on my way to the vault with the plants

Take them to Camp Forlorn hope.
Supply Sgt there gives the quest, I believe.

It's for the evil side of "How little we know". Pity we can't sell it off to gun runners if the other path in that quest is taken.

So...another useless piece of "item" I have to carry around, cluttering up an already cluttered backpack?
One thing I would wish for is...if the Quest is lost...the items are either sellable or dropable.

In this game...I REALLY hate clutter!
