Precision gauge blocks / jo blocks

Precision gauge blocks / jo blocks

These Made in Germany precision gauge blocks (81) go from .1001 up to 4" and each is marked with its specific size. All the surfaces are highly polished and very well coated with cosmoline or other protective coating. I do not think that a micrometer has touched any or have any been "wrung together". The Made in Germany metal tag and the number 20118 stamped on the inside and bottom is the only identification. The box is 14 X 8-1/2 X 2-1/4 inches and its weight is 7-1/2 pounds. I think there were decals applied with tape on the top because the finish is missing from one place. Tape remains on the other place. Please e-mail any questions or concerns.
