ok so i found this bottle and i'm trying to figure out what used to be inside it, it has a Capstan mark with D-522 and the numbers 13, and 6 on the bottom. it also says Full Pint, and the Federal Law Forbids the Sale or Reuse of this Bottle. it has a screw cap that is partly broke but looks like aluminum painted brown with a large K on the top and surrounded the K's all along the sides as far as i can tell pain is missing on parts
