The stamp on the back of the button is faint, but it appears to be 523. The zipper is stamped with Levi's, so it's likely from the 90s. There's no paper patch, but the silhouette suggests it's a 505. It should fit someone around 170cm tall and weighing 60-65kg. Please ask if you have any questions. Vintage enthusiasts are welcome.
