Description:
This gage is very similar in concept to the Fulton's Patent, (386,428) but instead of using alternately sharpened points to set the gain, it uses an adjustable point. This allows the gain to be varied at will (again, not a terribly useful feature, but interesting).

The big breakthrough on this tool was to make it of metal, and make the sides perfectly perpendicular to the edges. This allows this tool to be used as a simple square, allowing the craftsman to mark the sides of the butt mortise as well as the back. This feature, combined with the compact and sturdy nature of the tool, made it an instant hit with users.

This tool was originally produced by the Goodell Tool Company, which later became Goodell-Pratt. In the early twentieth century, the Miller's Falls Company bought Goodell-Pratt, and continued production of this tool under the Miller's Falls name until sometime around WW-II.
