One thing about accents is that they change over time. I'll give you an example. I have another friend from Reading, who is about the same age as me. He has a kind of London-ish accent, but nothing very strong. I met his late father, who was a lovely man, several times. He was also born and raised in Reading, but his accent had a distinct rural burr, not dissimilar to that of the great cricket commentator John Arlott. I doubt whether anyone from Reading has an accent like that now.
