Starrett Dial Bore Gauge Set in Metal Case

This item is a vintage Starrett dial bore gauge set, presented in its original, red-painted metal storage case. The set appears comprehensive, designed for precision internal diameter measurements. The main component, a dial indicator, is partially visible, held in hand, and clearly displays the 'Starrett' brand name on its cream-colored face, with black markings for measurements, indicating a range of 0-50 units (likely thousandths of an inch). The dial indicator itself exhibits some discoloration and minor wear consistent with age and use. The accompanying metal case, rectangular in shape with rounded corners, is finished in a faded and somewhat scratched red paint, showing signs of significant use and age. It features a simple metal latch closure mechanism on the front. Internally, the case is fitted with custom-cut foam inserts, which are now discolored, stained, and partially degraded, likely from oil, grease, and age; rust stains are noticeable in several areas of the foam, indicating the presence of ferrous tools and moisture exposure. The foam is designed to securely hold various bore gauge components, including extension rods of different lengths, an anvil, a micrometer-like measuring head, and other assorted small parts. Many of these metal components, particularly the larger ones, show visible signs of surface rust, pitting, and discoloration, suggesting a lack of proper storage or maintenance over time. Despite the cosmetic wear and rust, the general construction quality of Starrett tools is typically high, suggesting that with proper cleaning and calibration, the core functionality of the measuring instruments might still be intact. This set likely dates from the mid to late 20th century, given the style of the case and the appearance of the tools. This is a specialized precision measuring instrument, reflecting industrial or automotive-grade quality from its era.
