Measuring Square Appraisal

Combination Squares (Set of 2)

The image displays two combination squares, each consisting of a ruler (also known as a steel rule or blade) and a removable head. Both rulers appear to be made of stainless steel or a similar silvery metal, approximately 12 inches (30 cm) in length and about 1 inch (2.5 cm) in width. The markings on the rulers are visible, indicating measurements in fractional inches and potentially millimeters, a common feature for precision measuring tools. One ruler appears slightly darker and perhaps more worn than the other, suggesting differences in age or usage. The heads are cast iron or a similar sturdy black-painted metal. The left combination square features a standard square head, used for marking 90 and 45-degree angles, and has a thumb screw for locking it in place on the ruler. The right combination square features a square head combined with a spirit level (bubble level) integrated into its body, allowing for leveling and plumbing tasks in addition to angle marking. This level bubble is clearly visible. Both tools exhibit signs of use; there's a visible patina and some surface grime or dust on the rulers and heads, consistent with tools used in a workshop or industrial setting. No discernible maker's marks or specific brand names are visible in the provided image. The tools appear to be of a utilitarian quality, designed for practical application rather than ornamental display. Their general appearance suggests they are likely from the mid to late 20th century.
