Antique solid-brass wall-sconce / lamp component with an ornate pierced gallery cup and decorative back rosette. This appears to be a Victorian/early 20th-century lamp part (likely from a gas or kerosene wall bracket). The gallery cup has two opposing ring lugs and a pivoting/locking knuckle on a short arm, terminating at an ornate rosette backplate.
Stamped on the back around the center: “Pat’d … No. 625” (partially worn; see close-ups). Sold strictly for parts, restoration, or repurposing (props, steampunk builds, lamp-maker spares).

Projection (rosette edge to gallery rim): ~4.5–5 in (11.5–12.7 cm)
Gallery cup outside diameter: ~2.5 in (6.4 cm)
Back rosette diameter: ~2.25–2.5 in (5.7–6.4 cm)
As-found, unpolished brass with age-appropriate patina, verdigris, and oxidation.
