Gauge & Ring Sets

Contour and snap gauges sold together with the master setting ring they were ground to. The ring is what makes the gauge usable — re-mastering a gauge against a ring you do not have is not a practical job — so these stay as matched pairs.

Each pair is listed under its size and its class/reference letter, which is how the original shop told same-size sets apart. A few listings are the gauge only, with no ring; those say so plainly in the title and the description.

Used shop tooling, sold as-is, uncalibrated and without certificates.
