My grandfather’s shotgun. So old it has no serial number. US firearms law calls an antique like this a “curio”. And it is legal because serial numbers were not required when it was made. Shot with Nikon D850 using 3 studio strobes (2 octoboxes 90 degrees apart camera left and right as key lights, one striplight over the gun pointing down) Brought out details with Topaz. The black background was added in Photoshop.
