Is it sad that I noticed two rather glaring errors on Carter's file? It's annoying because normally I hate nitpicking...but I'm sorry: it's Royal Air Force, not British Air Force and it's interesting how she was in the SAS for four years and yet managed to leave a full year before it was formed...
Actually a full decade; it says she was a British Air Force nurse from 1934-6, in the Special Air Service from '36-'40, and in the Strategic Scientific Reserve from '40 onward.
Still, we are dealing with an alternate history here, a version of the Marvel Universe rather than the real universe. It has blatant and intentional discrepancies like the existence of Captain America as a well-known war hero and the role of HYDRA as a major part of the Nazi war machine, so there could easily be other discrepancies as well.
Oh and her phone number looks very odd too.
Well, yes and no. It's "020-7946 03560," which would work as a London number if you dropped the last 0 and wrote it as "(020) 7946 0356" instead. However, the file says Peggy lives in Winchester, whose phone numbers would use the dialling code "(01962)" followed by a 5- or 6-digit number.
