Wheel Truing / Static Balancing Stand with Dial Indicator

This item is a precision tool, most likely a wheel truing stand or a static balancing stand, designed for accurately checking the concentricity, roundness, or balance of rotating components. It is constructed primarily of metal, with a sturdy, rectangular black-painted base that appears to be made from sheet steel, featuring raised edges that form a shallow tray. Two vertical uprights, also made of black-painted metal, are securely attached to the ends of the base. Each upright supports a set of inverted V-shaped or roller-type bearings at its apex, designed to cradle an axle or shaft. The bearings themselves appear to be steel. The overall construction suggests a robust and stable design crucial for accurate measurements. A notable feature is the presence of a dial indicator mounted on the stand, attached via a magnetic base to a precision ground surface or a dedicated mounting block on the base. The dial indicator has a circular face with numerical markings and a needle, indicating its function in measuring minute deviations. Adjacent to the dial indicator, there is what appears to be a long, slender, polished metal shaft with conical or stepped ends, likely used as a mandrel or arbor for mounting components being tested. The item exhibits signs of typical workshop use, including some scuffs and abrasions on the black painted surfaces of the base and uprights, consistent with a tool that has been regularly handled. There are no visible major damages such as cracks or significant deformation, suggesting it remains functional. The polished metal components show some slight discoloration or patina but appear to be in good condition overall. The craftsmanship appears to be industrial quality, designed for durability and precision in a manufacturing or repair environment. The design esthetic is purely functional, typical of tools from the mid-20th century onwards. The specific maker's marks or model numbers are not discernible from the image.
