Gray knit cap (Fallout 4)

Gray knit cap is a piece of headwear in Fallout 4.

Locations
(Could be an Easter-egg from Leon the Professional. Next to the skeleton lies an empty milk bottle and a snub .44 revolver, the antagonists weapon from the movie.)
 * On the corpse of one of the dead scavengers on the bottom floor of Hubris Comics.
 * Beneath a skeleton next to a structure up the hill north of Concord, near a unmarked Raider fire-pit.
