This Old House

This Old House refers to an unmarked and repeatable quest in Fallout 3.

Speak with Winthrop in the Underworld at the Museum of History to unlock the option to bring him 5 pieces of Scrap metal to exchange for 1 Stimpak, 1 RadAway, or 1 Rad-X. This quest is very similar to Walter's Scrap Metal.

Behind the scenes

 * This quest is probably a reference to the American home improvement magazine and television series, This Old House.

Bugs

 * Sometimes, this quest may be permanently disabled, as when you show up and offer him scrap metal, the only available option for what to tell him is that you don't have any (regardless of whether you do or not).
