This is a standard steel trigger guard from a Winchester Model 70 rifle.
Bluing - 70% - The original bluing on this trigger guard is heavily worn. Since the fading is quite even throughout, it's actually a very decent-looking piece.
Metal - The metal is in very good condition with only a few slight scratches.
