Spanish American War Era US Army Haversack

Spanish American War era US Army haversack. The khaki cotton/canvas has some stains on it but is in overall solid condition. The metal hardware has some minor rust on it. The leather quaility is not good and it is starting to breakdown. The front of the bag has crossed cannons on the front with a 15 stenciled underneath. This indicates that this bag was a part of the 15th field artillery. There are other markings on it but they are had to make out. A makers mark could not be located.
