Would a '73 Norton Interstate come stock with a fiberglass gas tank without the side creases? From what I understand, Norton used some fiberglass tanks and fenders but I am not sure about this particular application.

I have never seen a factory fiberglass fender.
In 73 almost all tanks were steel including interstate, though a few glass ones were reported as "original". Like highriders......
