Three problems:
1) While Wee Baby Seamus is the one with the "archer" tattoo, if you darken his eye brows, it does visually convey a baby Archer.
2) I omitted Archer in prep school because the animators used his adult design.
3) The bootcamp clip might also have used an adult Archer, but I kept that clip since his face was turned away.
My personal take on watching it all in consecutively: The way Archer suppresses/distorts memories, his dad probably had a moustache, which doesn't narrow matters down much since Len Trexler and Major Jakov both rock them.
