L.S. Starrett Co. Outside Micrometer Set with Case

This item is a contained set of precision measuring tools, specifically an outside micrometer, along with a micrometer stand and a micrometer standard. The primary component is an outside micrometer, characterized by its "C" shaped frame, which appears to be made of cast metal, possibly cast iron, with a black crinkled or textured finish on the frame. The thimble and sleeve components of the micrometer are made of polished steel with fine knurling on the thimble for grip. The micrometer's measuring faces appear to be made of hardened steel. Markings indicating "L.S. STARRETT CO ATHOL MASS USA" are visible on the frame of the micrometer, indicating the manufacturer. The set is presented in a rectangular metal case with a red and silver exterior, suggesting a protective and organized storage solution. The interior of the case features custom-cut inserts, likely made of foam or a similar soft material, to securely hold each component. One side of the case lid is lined with black foam. Visible condition issues include some general wear and light surface scratches on the metal components and the case, consistent with age and use. There are no obvious signs of major damage or repair. The micrometer stand, also made of metal, has a 'U' shaped cradle for holding the micrometer, allowing for hands-free operation. The micrometer standard is a precisely ground cylindrical rod used for calibration and appears to be made of polished steel. The overall quality of craftsmanship is indicative of a well-made precision instrument designed for durable and accurate use in engineering or machining applications. The design suggests it is likely from the mid to late 20th century, given the style of the case and the visible finish on the micrometer frame.
