Starrett No 176 Pocket Gage Taper Thickness Gauge Appraisal

Vintage Starrett No. 176 Pocket Gage / Taper Thickness Gauge

This is a vintage precision measuring instrument, specifically a No. 176 pocket gage, likely manufactured by L.S. Starrett Co. or a similar high-end toolmaker of the mid-20th century. Constructed from polished tempered steel with a chrome or nickel finish, the tool features a unique fan-shaped pivoting mechanism. One side of the gauge includes a taper leaf (0 to 1/2 inch) for measuring the width of slots and holes, while the other side features a calibrated scale for thickness measurements in thousandths of an inch. The metal surfaces remain bright with well-defined, etched numerical markings and graduation lines. Notable features include the central pivot point with a decorative concentric ring design and the sharp, pointed taper leaf. The condition is described as 'like new,' and visually it appears to be in excellent functional order with minimal surface oxidation or scratching and no visible deformation to the precision edges. The accompanying leather case, seen in the background, is a protective sheath with a metal snap fastener, typical of professional tools from the 1940s to 1960s. The craftsmanship is indicative of high-quality industrial tooling, prioritizing accuracy and durability in a compact, portable form factor.
