Been with me for many years and traveled to many places around the world. My service number is engraved on both parts. This is probably the toughest canteen set in the world, it's just unbelievable how well made it is. No leaks guaranteed! Plastics and seal in perfect condition even though it must be at least 30 years old. It was second hand when I got it as a second water bottle 20 years ago. There is no pouch but fits in any USA canteen cover with the lid included. I've always properly cleaned it after use and dried internally for a couple of days before storing. Sad to see it go but although still serving I will never use it sadly. posted fast with royal mail.
