Description
An industrial brass escutcheon or rose plate intended for use with a cylinder lock. While it mimics the color of pale 10K or 14K gold, it is a functional architectural hardware component designed for security and aesthetics on doors, not for investment or jewelry purposes.
Key Features
Hexagonal/octagonal hybrid shape, countersunk screw holes, and 'ISEO' corporate branding.
Color & Finish
Pale yellow brass color with a polished but heavily weathered and pitted surface. There is visible oxidation and environmental patina/spotting.
Hallmarks & Stamps
Stamped with 'ISEO' (Brand) and 'MADE IN ITALY'. Note: It lacks any precious metal karat marks or fineness stamps (e.g., 750 or 18K), confirming it is industrial hardware.
Dimensions Estimate
Approx. 50mm x 55mm with a 30mm central bore and two mounting holes (standard cylinder size).
Gemstones & Inlays
None
Clasp & Closure
Screw-mount (two-hole attachment points for door hardware).
Chain & Links
N/A; Flat stamped plate construction with beveled edges.
Craftsmanship Details
Industrial die-stamping and machine-polishing. The lettering is stamped during the molding or pressing process.
Authentication Indicators
Red flags for gold: Lack of karat hallmarks, presence of surface pitting (typical of corroded base metals), and branding associated with a lock manufacturer rather than a jeweler.
Origin & Maker
Italy; manufactured by ISEO Serrature S.p.A., a known global manufacturer of locks and security products.
Era & Period
Contemporary Industrial (late 20th century to present).
Age Estimate
Likely produced within the last 10-30 years based on font style and logo.
Cultural Significance
Represents the Italian industrial design tradition of combining functionality with aesthetic finishes in home security hardware.
Condition Notes
Fair to Poor. Significant surface pitting, scratches, and oxidation. The finish has degraded due to exposure to the elements or high usage.
Value Estimate
$2 - $10 (Residual hardware value; zero precious metal scrap value).
Care & Maintenance
Clean with a mild brass cleaner or microfiber cloth. Do not use jewelers' rouge. Since it is oxidizing, a clear lacquer or wax could prevent further pitting.
