Brass centerfire ammunition in cardboard box

For sale are 990 rounds of brass casing 7.62x39. They are packaged in boxes of 15. I'm not sure of the manufacture as the boxes and headstamp are not marked. The case the ammo came in has a Rottweil (Germany) label on it. I'm not sure that is the original case. The rounds are bright, no corrosion. Overall, its good-looking ammo. Sold as is. Local pick-up only in the Columbus, Ohio area. Lot of brass-cased centerfire cartridges shown in an open cardboard box. Headstamps and box labeling are not visible in this photo, so manufacturer, caliber, and exact load cannot be confirmed. Primers appear sealed with red lacquer, suggesting older or sealed ammunition intended for moisture resistance.
