Civil War Reenactment Leather Belt with Pouch and straps with hooks

Description

I have no idea what this is used for but I will give you a description the best I can.
This is a leather belt of some type.  It was used in Civil War Reproduction.  There are two leather straps hanging from the belt with stainless hooks at each end.  I am referring to this piece as a belt but there is no buckle.  The length of the belt is 48". Someone added a 9" piece of leather to extend this item.  It can be removed.  The width is 1.75".
The two straps hanging from the belt are of different length.  One piece is 19" and one strap is 12".   There is also a metal hook attached to the belt.  I have no idea what that is used for.  If anyone reads this, I hope you send me information.
The bag that holds the belt is handmade and measures 7 x 6 x 2". I have cleaned this belt and bag but it does smell musty.
