This is a standard steel floor plate from a Winchester Model 70 rifle.
Bluing - 70% - This floor plate has factory bluing. There is significant edgewear and fading, a hint of light freckling, and one flurry of scratches that's completely removed the bluing in that spot. The finish on the hinge tab remains in decent condition.
Metal - The metal remains in very good condition with light scratches and freckling, but no significant damage.
