This is a featherweight aluminum trigger guard from a Winchester Model 70 rifle.
Finish - 95% - Possibly refinished. The finish on this trigger guard is dark matte black, and nearly perfect except for the edges of the bow where the bluing is scraped slightly. The finish could pass for original finish, though it's possible that it has been refinished.
Metal - There are no notable scratches, dents or other defects to the metal.
