I purchased this about 4 years ago. I've used it about 10 times, and there are no noticeable scratches or stains. The size is marked as M on the main body, but the actual size is L. Based on the mil-spec, I estimate it's a late-model M-65 from 1974. *Please note that this is an amateur assessment, and I cannot guarantee its authenticity. [Product Description] The number of these items is decreasing year by year, and their value and price are increasing. The M-65 is popular among celebrities like Masaki Suda and in the vintage clothing scene, and it's no exaggeration to say it was a driving force behind the vintage clothing boom.
