This is an import outside micrometer set from 0-1" thru 5-6" with standards to calibrate the mics before using them. They all have carbide anvils, ratchet thimbles, spindle locks, and read in .0001" increments. This set comes in the original wood storage box. A couple of these were lightly used, but most have never been touch. This set is in excellent condition and all of them move freely.
