Very beautiful bicycle!
Your English is as good as anyone's, so don't worry about that.
And this is most definitely the place to post photos of that bicycle. We love them.
I agree, it looks pre-Raleigh to me; the later ones say "Nottingham" where this one says "Birmingham." The twin top tube design seems earlier as well, but I don't know the details about that.
As for Platex, I know nothing.
