It says "Made in Italy" on the box.Here you go.
I picked these up several years ago when a friend passed.
I got about 1k of these, and some even older looking.
I'm using them in my in-line muzzleloader now.
Haven't had the first failure and I've been through almost 100 of these.
Check out the label closely.
Don't know if they were made in Indiana or just distributed from here.
Anyone care to guess a date?
I have no clue.
