OK, I always feel stupid asking this question, but does this underlined 5 make this Dunhill a 1955 (because the underlined 5 is smaller than the letter D in England) or is it a 1965 (because I have seen reference where a 1955 will NOT have an underline, but a 1965 may or may not). I am guessing it is a 1965 because a 1955 would NEVER have an underlined number, just a small number. Is that correct, this is a 1965?
