This is a vintage aluminum army canteen, marked "PSL60" on the cap. It's a classic piece of military surplus, ideal for collectors or as a rustic water bottle for outdoor adventures. The "PSL60 canteen" refers to the West German Army (Bundeswehr) M59 canteen and mess tin set manufactured in 1960 (PSL stands for Präge-Stempel or production stamp, and 60 is the year). These collectible Cold War-era sets feature an aluminum canteen, and a green cover. The canteen is in good used condition with visible wear and tear, including scuffs and scratches consistent with its age and use. The cap is securely attached by a leather strap, though the exact capacity is unknown. It presents a robust, old-school charm.
