This is a standard steel trigger guard from a Winchester Model 70 rifle.
Bluing - 80% - The original bluing on this trigger guard shows little edgewear or thinning, but it contains significant scratches and scuffs to the top of the bow.
Metal - The metal is excellent condition, with no notable damage. The scratches and scuffs in the bluing do not appear to extend into the metal.
