Description:
A classic in marking gage design, and rightfully so. The Barrett Patent gage is a wonderful tool, being very easy to use, accurate, and robust.

These tools were produced by several different companies over the years, but the only ones known marked with the patent date were those by Goodell-Pratt. The Leavitt Manufacturing Company manufactured similar pieces using a different locking mechanism patented by Barrett a few years later (530,468), but these were still marked with this patent date.

Goodell-Pratt also offered this tool in 1-arm and 3-arm configurations, which are somewhat more scarce than the other models.

This tool was in production for many years, and was quite popular. It is widely available on the old tools market, and quite often found "in the wild".
