Art Deco Style roll-top container, Antique

Gifted to me in late 1980s from Antique Dealer friend of my parents. I kept jewelry in it and I thought it was a container for powder for a dressing table but several people have said it’s an ashtray. Made of Enamel, chrome and in excellent shape. Please see all photos for any chips in the paint or other flaws as they are part of the description
