A large-range outside micrometer combining a Mitutoyo thimble and spindle assembly with a Scherr-Tumico cast iron frame, covering a 14 to 15 inch measurement range. The Mitutoyo spindle bears the label "14 inch" on its barrel grip. The Scherr-Tumico frame is marked "14-15 In." with the internal reference "W/G," and the brand diamond logo is cast directly into the frame body. The complete assembly is stored in a fitted wooden case with custom-cut cradles supporting both the frame and the spindle assembly.

The Mitutoyo 103-191 is a Series 103 mechanical outside micrometer with a ratchet stop thimble for consistent measuring force and repeatable readings. Resolution is 0.001 inch. The frame features a hammertone baked-enamel finish. Scherr-Tumico, based in St. James, Minnesota, was a longstanding US manufacturer of large-capacity precision measuring instruments, and their frames are known in the industry for dimensional stability and durability.

This combination of Mitutoyo spindle hardware and Scherr-Tumico frame is consistent with field-assembled or factory-paired configurations used in heavy manufacturing and inspection applications where large outside diameter measurement is required. Suitable for use in steel mill, foundry, aerospace, and heavy machining inspection environments.
