Made by Queen in PA between 1960-1970 (no tang stamp), has fake Winterbottom (named after the man that came up with the jigging pattern) bone scales and 440A or C stainless steel. Queen 86ed last year after a bunch of screw ups on their part.
Queen made fine knives for a long time, went through a few ownership changes, and their latest owners let QC and standards slip until they went under. While you have a fine specimen there, it isn't a very valuable knife, but I doubt you care much about that. It's a nice piece from a different time.
