Brass Rosette with Knurled Knob

This item appears to be a solid brass rosette, circular in shape with a raised central elliptical section. The outer rim of the circular disc features a series of eight radiating, raised segments, resembling spokes or beams, each with parallel etched lines, giving a corrugated or textured appearance. The central elliptical section is perfectly smooth and flat. Protruding from the very center of this elliptical section is a short, cylindrical brass knob with a finely knurled surface, indicative of a part designed for grip and rotation. The overall color is a uniform golden brass, showing some subtle variations in sheen due to direct lighting, but no significant tarnish or heavy oxidation is immediately apparent from the image. The surface appears relatively clean, with a slight luster expected of polished brass. There are no visible maker's marks, stamps, or significant engravings on the top surface. The construction suggests it could be a decorative element or a functional component, possibly a specialized knob, a base for a finial, or part of a mechanical device. Given the material and design, it likely dates from the early to mid-20th century, though without further context or markings, a precise age is difficult to ascertain. The craftsmanship appears to be of good quality, with precise machining evident in the knurling and the crisp lines of the radiating segments.
