Could have been and "attribute" or hard check fixture. 5/8" nominal hole size with built in tolerance, or MMC (max material condition) allowance. So it it would equate to a 0.015" true position allowance if 5/8" is really the nominal holes size. I'd be surprised if it was that close back in the day.
