Vintage Industrial Brass or Gold-Plated Mechanical Component
Mechanical Part/Finding (Potential Tie Clip or Industrial Component fragment) · Yellow hue (suggestive of brass alloy or gold-toned coating).
Purity: Indeterminate; likely base metal (brass) or low-karat gold plating (less than 10K or GF). Visual evidence suggests lack of high-purity gold content due to surface oxidation and dull luster.
Type
Mechanical Part/Finding (Potential Tie Clip or Industrial Component fragment)
Purity
Indeterminate; likely base metal (brass) or low-karat gold plating (less than 10K or GF). Visual evidence suggests lack of high-purity gold content due to surface oxidation and dull luster.
Gold Type
Yellow hue (suggestive of brass alloy or gold-toned coating).
Weight
Estimated 2.0 to 3.5 grams based on its apparent flat, stamped metal construction and relatively small volume.
Description
This item is a functional metal component, possibly a specialized spring-tension arm or a fragment of a vintage tie bar mechanism. It features a bi-level stamped design with a circular rivet/fastener on one end and a distinctive offset 'step' in the center. The surface has a industrial brushed texture rather than a refined jeweler's polish.
Key Features
Raised circular rivet, center-pivot step-down, brushed texture, and rounded terminals.
Color & Finish
Brushed/satin finish with visible vertical grain. The color is a muted, greenish-yellow consistent with brass or aged architectural bronze, showing distinct patina and oxidation spots.
Hallmarks & Stamps
None visible in the image. The absence of hallmarks on a flat, accessible surface typically indicates a non-precious base metal or a generic industrial component.
Dimensions Estimate
Length: 35-45mm; Width: 5-8mm; Thickness: 1-1.5mm. Standard small-scale industrial part size.
Gemstones & Inlays
None present. Features a raised circular rivet or button-head fastener on the left side.
Clasp & Closure
Mechanical hinge/pivot point at the center with a stepped-down profile. Not a jewelry clasp, but likely a cantilever or leaf-spring mechanism.
Chain & Links
N/A; solid stamped metal strip construction.
Craftsmanship Details
Machine-stamped from sheet metal, finished with a mechanical wire-brushing, and assembled with a single-point rivet fastener. Pragmatic industrial construction.
Authentication Indicators
Red flags for solid gold: Greenish undertones, lack of high-luster reflection, lack of hallmarking on a flat surface, and uneven surface oxidation (brassing). Likely brass or bronze.
Origin & Maker
Unknown; likely an OEM (Original Equipment Manufacturer) hardware component for electronics, furniture, or apparel.
Era & Period
Mid-20th Century (circa 1950s-1970s). The stamping and riveting techniques are consistent with mid-century mass production.
Age Estimate
Likely 40-60 years old based on the oxidation patterns and mechanical design.
Cultural Significance
Represents the era of post-war industrial manufacturing where functional components were designed with both utility and aesthetic finishes.
Condition Notes
Fair. Significant surface oxidation, darkening of the metal (patina), and visible grime on the right edge. Structure appears intact but functionally isolated.
Value Estimate
Negligible ($0.50 - $5.00). Value is primarily functional or as scrap brass. No significant melt value or numismatic premium.
Care & Maintenance
If brass: Clean with a mild metal polish or lemon juice and baking soda to remove oxidation. If gold-plated: Use a soft damp cloth only; avoid abrasives that will strip the thin gold layer.

Interesting Facts
Brass 'gold-tone' items were frequently used in mid-century design to mimic the look of solid gold at a fraction of the cost for functional hardware and accessories.
