This is a vintage laboratory or apothecary beam balance scale, likely dating from the early to mid-20th century. The scale is mounted on a solid, rectangular dark-stained wood base, which features an integrated metal holder with six circular recesses designed for holding fractional weights (weights are currently missing). The mechanical assembly consists of a metallic beam graduated with measurement markings, supporting two circular, shallow stainless steel or nickel-plated weighing pans. The construction exhibits a sturdy industrial design characteristic of Ohaus or similar scientific instrument manufacturers of the era. The metal components show signs of oxidation, surface grime, and light pitting, consistent with age and use in a workshop or laboratory environment. The wooden base shows some softening of the edges and surface wear but remains structurally sound. A distinctive feature is the central decorative metal support under the beam, which may contain a stylized manufacturer's logo. This scale represents a utilitarian measurement tool built for precision and durability prior to the digital era.

Based on my visual examination of the provided images, this object appears to be a vintage beam balance scale, likely produced in the mid-20th century (circa 1940s-1960s). It shares strong design characteristics with models produced by Ohaus, specifically the 'Harvard Trip' series or similar student/laboratory balances, which were ubiquitous in educational and pharmacy settings. The scale features a solid wooden base with recesses for a weight set, though regrettably, the weights are missing, which negatively impacts the complete set value. The metal components—including the dual pans and the graduated beam—show moderate oxidation and surface grime consistent with age and probable storage in a non-climate-controlled environment. While the structure appears sound, the finish is worn. In the current market, these scales are relatively common due to their durability and mass production for schools. They are primarily valued today as industrial décor or prop pieces rather than functional scientific instruments. Comparable sales for incomplete units in this condition generally fall in the lower range. A mint-condition example with original weights might fetch significantly more ($100+), but the missing components and surface pitting limit this specific piece's value. It is important to note that without physical inspection, I cannot verify the mechanical action of the balance beam or the accuracy of the zero-setting mechanism. A hands-on test is required to ensure the knife edges are not dull or damaged, which would render it non-functional.
