This is a nice vintage 4-5"capacity micrometer with .0001" increments and accuracy. It also has a friction thimble for better accuracy. It's in great shape. Little signs of use. The hardwood box is lap-jointed on the corners, clean and very solid, good sliding track for the top to close the box. A gauge and wrench are inside along with an Allen wrench for calibration. The box label is marked Made in Poland N864 228005. Overall 98% like new condition.
