Vintage mechanical balance scale component

This object appears to be a heavy industrial or kitchen mechanical balance scale, or at least a significant portion of one. The item is constructed primarily of cast metal, likely iron or steel, and features remnants of a green-tinted paint. An inspection of the visible markings reveals a stamped numerical '2' on a flat horizontal arm and a diamond-shaped logo on a round component. The owner notes unverified markings including 'Sif no1 base' and 'no 2 on balance arm.' The object is in poor condition, exhibiting significant surface oxidation, rust, and pitting across nearly all visible surfaces, suggesting long-term exposure to moisture or storage in an unprotected environment. The mechanical joints appear frozen or heavily encrusted with corrosion. Such designs are stylistically consistent with late 19th or early 20th-century utility scales. Without a fully legible manufacturer's nameplate, the specific brand cannot be determined from the images alone; it is categorized based on its visible utilitarian mechanical form and cast-metal construction.

Based on my visual analysis of the provided image, this item is a heavily corroded cast-metal component of a mechanical balance scale, likely dating from the late 19th to early 20th century. While the owner identifies this as a 'Sif no1 base' with a 'no 2 on balance arm,' I cannot visually confirm the manufacturer or model from the photograph. The item bears markings that appear consistent with those descriptions, and the diamond-shaped logo is a common characteristic of industrial hardware from that era, but these features are not sufficient to confirm a specific maker without further physical cleaning and inspection. The object is in poor condition, showing extensive oxidation and structural pitting which likely renders the mechanical joints non-functional. Based on what I can see, the value is primarily in its aesthetic appeal as a rustic or industrial decorative object rather than as a functional tool. The suggested estimate of $15—$35 assumes the item is an unattributed industrial artifact in its current 'as-is' state. If the attribution to a specific collectible brand like 'Sif' were to be substantiated by an in-person examination and the cleaning of the nameplate, the value could potentially increase slightly to $50—$70 for a specialized collector. Conversely, if the metal is found to have structural integrity issues or if it is a later mass-produced reproduction made in the style of antique scales, the value would drop to a nominal decorative level of under $10. To confirm its origins and functional potential, one would need a physical inspection by a specialist in antique hardware to verify the depth of the corrosion and the legibility of any manufacturer hallmarks.
