Original unbranded door-knocker prop with a pale warm brass finish, rounded D-shaped ring, stepped oval backplate and domed lower striker. Includes a straight retainer barrel, bored bushings and collars, and two open mounting holes. Supplied in its static assembled pose for architectural scenes. Overall posed dimensions are approximately 111.3 mm wide, 170 mm long and 44.4 mm deep. The model has 14 separate mesh parts and 25,200 triangles. Original surface maps provide color, roughness, metallic response and tangent-space normals. The UVs share material space; this is not a unique lightmap atlas.

The mesh contains 12,608 vertices. Packages: native Blender 5.2 with Cycles, FBX 7.4, OBJ/MTL and glTF 2.0, including the required original image textures. FBX and OBJ shader interpretation can vary; a material-only helper is supplied where supported.

Created with AI-assisted Python and Blender, with original geometry and mathematically generated material maps. No third-party mesh, CAD, reference photographs, logos or manufacturer files are included. Static visualization asset without rigging, animation or a working hinge simulation. Mounting fasteners are not included; no brand, certification, engineering or 3D printing claim.
