Vintage LINKS Harbin 150 mm Gauge Block – Class 1, with Wooden Case

A piece of late-20th-century precision engineering: a LINKS Harbin 150 mm gauge block with a wooden storage case, documentation, and a factory inspection slip. According to the seller, both available examples are new, unused old stock (NOS), still in their original protective grease.

Gauge blocks provide a fixed length reference for checking and setting measuring tools. An instrument like this evokes the traditional inspection room, where physical reference standards helped machinists check their work. It is also an interesting addition to a collection of vintage precision tools.
