Art style: History stickman.
Detailed close-up of the first visible bronze gear inside the mechanism after corrosion removal. On-screen label appears. Sharp overhead lighting. The mood is surprising and technical, with bronze and shadow tones.

FINAL STYLE ENFORCEMENT (this is the authoritative rendering directive — it overrides any style wording elsewhere in the prompt):
Render this image entirely in "History stickman" style. Match the lighting grammar, material response, colour science, level of realism / stylisation, line weight, and shading model typical of "History stickman". Keep the subject, composition, camera angle, lighting direction, and colour palette from the description above — but EVERY surface, skin, fabric, material, and environmental element must be rendered in the "History stickman" idiom, not in any other medium.
