Yes thats NOT a crossbow, its a compound bow. That's an OLD Indian Archery "Hunter" model bow I'd guess the vintage of to be in the late 70s-early 80s. Indian Archery became XI in the mid/late 80s. (Their parent company now owns Bear Archery among many others)

The bow is essentially worthless unless someone has an emotional attachment to that model (maybe they had one many years ago) or they want to hang it on the wall at their hunting cabin for decoration. I'd say $10-$20 tops. I certainly WOULDN'T fire it until someone replaced the cables & string. (Which would cost more than the bows worth)

The case is missing the piece that would allow it to hold arrows. That case would be worth $20-$30.
