Outside Micrometer in Wooden Case

The item is a precision outside micrometer, housed within a fitted wooden case. The micrometer itself features a 'C'-shaped frame, primarily black in color, with a satin metallic thimble and spindle assembly. The frame appears to be made of cast metal, likely steel or iron, with a textured, possibly crinkle, finish that is generally well-preserved. There's a visible marking '0-1' on the black frame, indicating its measurement range, likely 0 to 1 inch. The spindle and thimble show some minor surface wear consistent with use, but no significant corrosion or pitting is immediately apparent. The visible parts suggest a robust construction, typical of precision measuring instruments designed for durability and accuracy. The wooden case, made of a light-colored hardwood exhibiting prominent grain patterns, is designed with a custom-routed recess perfectly shaped to cradle the micrometer. There are also two smaller, elongated recesses carved into the wood, likely intended for a calibration standard (gauge block or rod) and a spanner wrench, neither of which are present in the image. The wood itself shows some minor scuffs and marks on its surface, indicating handling over time, but generally appears solid with no visible cracks or serious damage. The case has a simple hinge mechanism, suggesting it opens fully to display its contents. This type of micrometer and case setup is indicative of a tool used in mechanical engineering, machining, or quality control, likely dating from the mid-20th century onwards given its general appearance and material choices. The craftsmanship of both the tool and the custom-fit case points to a focus on protecting and presenting a precision instrument.
