Commonwealth Weaponry

Commonwealth Weaponry is an unmarked location in the Diamond City market $$ It is owned and operated by Arturo Rodriguez as a weapon shop offering "hand-tooled" weapons, ammunition, weapon modifications, and various recommendations to passersby and interested clients. The shop is stated to be open "8 days" (per week).

Layout
This building has two levels and three entrances: a ground-level door to Arturo's house inside his small covered shop stall, a second ground-level door to the house on the north side of the building on Third Street, and a door on the roof to a trailer comprising a separate attic area of the house. The stall also features three ammo boxes, a duffle bag, and a toolbox, with a weapons workbench to the right.

The main section of Arturo's house consists of a first-floor living area with several more ammo boxes and other containers and an owned bed, and a small upstairs sleeping area used by Arturo's daughter Nina with an owned mattress. The separate attic area in the trailer on the roof, which can be reached by jumping across the buildings and canopies to the north, contains yet more ammo boxes and other containers. There is a house cat outside on the (perhaps hot) tin roof.
