This is a standard steel trigger guard from a Winchester Model 70 rifle.
Bluing - 70% - The original bluing on this trigger guard shows moderate edgewear and fading across the entire part. The wear is smooth and consistent, and as a result it is still a very attractive piece. There are no deep scratches, dents, or other serious cosmetic flaws.
Metal - The metal is in excellent condition, with some very slight rust/pitting.
