Scrap Metal (слэш)

Steve and Bucky write each other during the war. With more than your usual inclusion of spam & jam sandwiches, chickens, radar-evasion devices, Dum Dum Dugan's hat, and that dumb lunkhead who plays Captain America. Who's that, Steve? Oh, just some guy I work with.
Title is a reference, in part, to this scene from The First Avenger--
Bucky: Why are you so keen to fight? There are so many important jobs.
Steve: What am I gonna do? Collect scrap metal...
Bucky: Yes!
Steve Rogers: ...in my little red wagon.
Bucky: Why not?
Note: tinzelda writes Steve's letters; Scappodaqui writes Bucky's.
