In that case you were asking the wrong question.
You asked what we thought a purist would say, and how would we know, not being mind readers? The question should have been "If *you* are a purist, would you say that (Caley Fairburn) in preservation is prototypical?" As you can see, prototypically, questions need question marks to indicate the interrogative mode. Otherwise it sort of looks like it is dressed up to be a question, but it isn't really.
And how would you then know if the answers were coming from real purists, eh? They might be fake purists pretending to act like prototypical purists to confuse the unwary.
You can't be too careful in these situations.
However, I am a real, genuine, purist. Honest, guv. And the Caley Fairburn in preservation is prototypical, but not *typical". That is, in and of itself it carries a prototype livery (its own), but that livery is not typical of what it represents. Rather, the livery is whimsical, and should only be considered within its own context. I think that makes it artistically self-referencing, which always trumps mere technical representation. Rather like my layout, actually.
