jen's time travel steve rogers/bucky barnes fic recs

swapped through time

• Locked Doors by 74days [Steve Rogers wakes up to find his best pal Bucky missing and a fella that looks just like him in his place. It seems that something weird is going on, and this new Bucky has a plan of his own.]
• to memory now I can't recall by Etharei [While on a mission storming a HYDRA facility, James Buchanan Barnes touches one of the many strange alien devices collected by the Red Skull. He does this, in fact, twice— in the past, and in the future. Next thing he knows, Bucky Barnes is opening his eyes in the 21st century, which is full of great gadgets and coffee, and at least includes his old pal Steve. (And, inexplicably, a different Stark.) Meanwhile, the Winter Soldier finds himself in the middle of World War Two, helping Captain America hunt down HYDRA (which is at least familiar), pretending to be Bucky Barnes (which is not), and figuring out the very noisy group of soldiers who call themselves the Howling Commandos.] 
• To Live It Again Is Past All Endeavor by trinityofone [Time travel bodyswap! Present-day Steve and Bucky wake up back in their old bodies in 1938, while past Steve and Bucky wake in a future where they're both built like comic book heroes and Bucky's got what he thinks is a swell future robot arm. Adventures are had, and the ethics of time travel are debated. Also, everyone trash talks Willem de Kooning.]
