Beautiful fire arm you have there.
My tribe loved that gun and if you look at historical photos of a lot of Native warriors you'll notice how we use to alter them, we would use brass tacks that we traded from the french fur trappers and we would decorate the stock & forearms with the tacks, but they also served a purpose for us, the helped with the grip on the rifle when it rained or got blood soaked in battle.
I'm a BIG fan of the old style repeaters.
I know you will enjoy shooting that long gun, congratulations on a very wise choice.
I hope to some day get my hands on a Henry repeater and yes, out of tradition I will be adding the tacks.
