Produce a quiet museum display film for a fictional 19th-century brass navigation instrument. Preserve the object's shape, engraved marks, patina, scratches, and missing fastener exactly from Images 1–4. Do not restore damage or invent readable inscriptions.

Opening: controlled macro view of the worn adjustment wheel under neutral conservation light. Middle: camera travels slowly across the engraved arc while a narrow highlight reveals tool marks; transition into a restrained silhouette of a shipboard table, clearly presented as atmospheric interpretation rather than historical reconstruction. Ending: return to a full three-quarter object view on a neutral support, leaving clean space for curator-approved captions added in post.

Sound intent: quiet gallery air, soft wood creak, no dialogue or dramatic score. Keep the artifact static, scale consistent, and reflections physically plausible. Avoid hands operating the fragile object, fabricated dates, national symbols, readable generated labels, restored polish, sensational adventure imagery, or watermark.
