Ron,
Yes, and sometimes I wish I still had two of them!
You mention knowing of a half of a frag sleeve in the U.S. What state might that one be in? I was in Arizona last month visiting a friend and discovered an egg grenade with half of a sleeve in his collection. I was especially surprised to see it as I know of another grenade and partial frag sleeve just like it about 150 miles away in another Arizona collection.
Here's the one observed last month:
And the other one photographed last year. Those are actually two different items although you would swear it is the same one in both photos. Like twins!
By the way, it's always nice to see the photos of that case of stick grenades. Just beautiful.
