4-40-NC-3 Go/No Go Ring Thread Gage Set.
We have a number of these gages from the close down of a local company. All the gages came from the inspection tool crib, and were originally in sealed bags. Some units from the crib were new with wax and others look like they were put back for future use. Some may be old, but all look to be in usable condition. Do not see any inspection tags on any of the gages. Several different manufacturers.
