Some of the suede and rubber may have been rubbed and marred slightly due to shifting against other objects; there may be dust, debris, etc. That accumulates on fabric over time. Modify to a Star Wars-type fighter pilot look?
Just keep in mind a large-size head mightve been smaller in the 1940s than it is today! Return in same condition within 30 days if not satisfied.
