Vintage Measuring Tool Appraisal

Vintage Depth Gauge

This item appears to be a vintage depth gauge, likely used in woodworking, machining, or metalworking for measuring the depth of holes or recesses. It consists of a flat, elongated metal rule, approximately 6 to 8 inches in length, with clearly marked numerical measurements and incremental lines. The material appears to be steel or a similar robust metal, exhibiting a dark, aged patina which suggests significant use and age. One end of the rule features a fixed 'foot' or shoulder, set at a right angle to the main body, allowing the user to rest it on a surface while the rule descends into a measurement area. The markings on the ruler are faint but discernible, showing increments from 0 to 6, likely in inches, with smaller subdivisions. The overall condition indicates wear consistent with an antique or heavily used tool; there are no obvious signs of significant damage like bends or severe corrosion, but surface abrasion, discoloration, and slight loss of clarity in the markings are present. The craftsmanship appears functional and utilitarian, designed for precision rather than aesthetics. The lack of distinct brand markings or manufacturing details prevents a more precise dating, but its design suggests a period from the early to mid-20th century. The simplicity of its mechanism and solid construction point to a durable and reliable tool of its era.
