It was a pre-war Stucky story with always-a-girl!Steve. Stucky was married when they went to the Expo where they met Howard. Stucky and Howard became friends and both Bucky and Steve (Steph?) are injected with the serum eventually, but I think Bucky was first. Sarah Rogers and Mrs. Barnes were featured as was the Rogers' Irish heritage. Lots of Irish endearments from the characters, especially Bucky (he picked it up from the Rogers.
Any help would be greatly appreciated. Thanks!!!!!
