This is a standard steel trigger guard from a Winchester Model 70 rifle.
Bluing - 85% - The original bluing on this trigger guard shows almost no edgewear. There are small areas of thinning in the bluing, a few rubs and light scratches, and a very fine line that runs across the width of the bow.
Metal - The metal is excellent condition with the exception of a few scratches and tool marks.
