Pair of M&W 8″-12″ Interchangeable-rod Micrometer Sets in Fitted Cases (certificate + tools)

Two M&W 8″-12″ interchangeable-rod outside micrometer sets presented in their original fitted foam cases — M&W logo and 8″-12″ range plate visible. Both sets include the full series of yellow-sleeved extension rods, several spindle/adapters, adjustment wrenches and a calibration certificate; spindle/thimble action was checked and found to run smoothly.

These are classic workshop measuring sets for engine, shaft and large-blank inspection where 8″-12″ range coverage and changeable rods are required. Suits a metalworking shop, toolroom, maintenance department or a buyer looking to add an economical pair of large-range mechanical micrometers to their kit. The included calibration certificate and adjustment tools make these useful to technicians who need a usable set immediately or to re-certify quickly.
