AI Appraisal Estimate

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.

I have carefully examined the provided image of this vintage Starrett dial bore gauge set. Authenticity, based on the clear 'Starrett' branding on the dial indicator, appears solid, a hallmark of quality from a reputable manufacturer, likely mid to late 20th century. However, definitive authentication would require an in-person inspection for serial numbers and construction details. The overall condition is fair to poor. The metal case exhibits significant cosmetic wear with faded paint, scratches, and a functional but basic latch. Crucially, the internal foam inserts are heavily discolored, stained, and degraded, with prominent rust stains—a clear indicator of moisture exposure and neglect. Many of the metal components, including extension rods and the measuring head, show visible surface rust, pitting, and discoloration, which will undoubtedly affect their precision and functionality. While Starrett tools are known for their high quality, the extensive rust and degradation are major concerns. Comparables for complete, well-maintained vintage Starrett bore gauge sets can range from $200-$500, with new sets costing significantly more. However, the condition of this specific set, particularly the rust on critical measuring surfaces, drastically reduces its value. The demand for these specialized tools remains, particularly among machinists or collectors, but this set would require extensive cleaning, restoration, and likely recalibration to be fully functional, which adds a substantial cost. The primary impact on value is the poor condition of the tools themselves, especially the rust. Without physical inspection, I cannot ascertain the depth of the pitting or whether the internal mechanisms of the dial indicator or measuring head are corroded or compromised. Therefore, I estimate its value primarily as a restoration project or for parts, placing it in the $75-150 range. A full assessment would require hands-on examination to check for free movement, accuracy, and the extent of corrosion damage beyond the surface.
