Nickel-Plated Steel Hub Brake Component or Automotive Bracket
Mechanical Component (Non-Flatware/Hollowware) · Unknown Industrial Manufacturer; identified by part number 'P01M 1827'
Pattern: Industrial Production; marked with part identification number P01M 1827
Type
Mechanical Component (Non-Flatware/Hollowware)
Maker
Unknown Industrial Manufacturer; identified by part number 'P01M 1827'
Material
Nickel-plated steel or zinc-alloy casting; lacks precious metal fineness or hallmarks
Dimensions
Approx. 2.5 inches in length; weight estimated at 40-60 grams; high density characteristic of base metal
Description
An industrial mechanical bracket, likely a component of a drum brake assembly or a mounting plate for a hub-indexed gear. The item is not a silver decorative object but a functional hardware piece featuring mechanical wear and industrial plating.
Key Features
Three circular mounting apertures, alphanumeric industrial stamping, and heavy mechanical scratching
Material & Composition
Nickel-plated steel or zinc-alloy casting; lacks precious metal fineness or hallmarks
Finish & Decoration
Industrial plating with significant mechanical abrasion, scouring, and surface pitting
Hallmarks & Stamps
Lacks silver hallmarks (no lion passant, .925, or maker cartouche); features stamped alphanumeric serial 'P01M 1827'
Construction Details
Precision die-cast or stamped heavy-gauge metal with machined aperture holes for mechanical fastening
Functional Features
Fastening points (apertures) for bolts/screws and a curved mounting profile for cylindrical fitment
Handle & Grip Details
N/A; this is a mounting bracket without manual grip features
Craftsmanship Details
Mass-produced industrial quality with rough edges and non-aesthetic functional finishing
Authentication Indicators
The presence of alphanumeric industrial stamps and the lack of purity marks confirm this is not fine silver or sterling
Origin & Manufacturing
Mass-manufactured industrial facility, likely associated with automotive or bicycle braking systems
Era & Period
Contemporary Industrial/Automotive (Late 20th - 21st Century)
Age Estimate
Circa 1990-present day; based on the modern sans-serif typeface of the stamp
Cultural Significance
Represents the mass-produced nature of 21st-century mechanical engineering rather than artistic silversmithing
Condition Notes
Poor for silver standards; heavy gouging, plating loss, and evidence of mechanical stress. Grade: Junk/Scrap Hardware
Value Estimate
Negligible; scrap metal value only ($0.05 - $0.20 range)
Care & Maintenance
Requires anti-corrosive oil if intended for mechanical use; not suitable for silver polish
