Pulled a Weaver K-4 Classic, 4x38mm Dual-X scope (model 849415) off of a Marlin 336 a few years ago and just found it again on the bottom of my ammo chest. Happy find! Was trying to determine it's value but every single web page where it's listed just states "discontinued." Not an Ebay fan. So with very minor hunting blemishes, what's it worth in y'alls opinion? Thanks!
