Vintage blued double-action revolver with holster

Vintage blued double-action revolver with a long barrel and exposed ejector rod, shown with what appears to be an older leather holster. The revolver has a swing-out cylinder and fixed sights, with aftermarket or period grips featuring a decorative/medallion-style inlay. Overall appears used with typical handling wear consistent with age. Exact make, model, and caliber are not identifiable from this single photo and would require close-ups of barrel and frame markings. A solid candidate for a classic revolver collector, display piece, or restoration project depending on mechanical condition.
