Porcelain caster wheel and socket

This item is a vintage or antique furniture hardware piece, specifically consisting of a white glazed ceramic or porcelain roller wheel housed within a matching square ceramic socket block. The overall color is a glossy off-white or cream, exhibiting a smooth finish with minor surface wear and small discoloration spots consistent with age and prior use. The cylindrical roller wheel is positioned within a recessed channel in the square housing block, designed to allow smooth rolling motion while supporting vertical weight when installed on a piece of furniture such as a heavy wooden cabinet, piano, or work table. There are no clearly visible maker's marks, stamps, or legible text directly discernible from the primary image angle, leaving the exact manufacturer unverified. The owner has provided additional context stating 'Singh ideal junior Milwaukee Wisconsin', but this user-supplied attribution is entirely unverified by visual text within the photograph and remains unauthenticated. Stylistically, this hardware piece is consistent with industrial or domestic hardware dating from the late 19th to early 20th century. The construction appears sturdy, featuring thick-walled ceramic designed to prevent floor scratching and provide high load-bearing capacity without rusting.

Based on what I can see in the photograph, this item is a vintage porcelain caster wheel and socket featuring an off-white glazed ceramic roller housing, consistent with hardware dating from the late 19th to early 20th century. The owner's notes state that this piece is associated with 'Singh ideal junior Milwaukee Wisconsin,' but I can't verify from a photo whether this attribution is accurate, as no maker's marks are legibly discernible from the primary image angle. My appraisal value assumes the user-supplied attribution is correct; however, because visual examination alone cannot determine exact manufacture or period without physical inspection, this remains a working assumption. General market demand for architectural salvage and vintage hardware is driven by restorers seeking period-appropriate components, with comparable unmarked porcelain casters typically trading in the $20 to $40 range. If the piece is ultimately found to be a reproduction, replica, or unattributed, the value would likely sit closer to that lower baseline. To move beyond an estimate, one would need physical inspection to check for subtle underglaze markings, alongside potential expert hardware appraisal. Without such authentication, the higher end of the estimated $45-75 range remains dependent on the unverified attribution proving correct.
