Description:
An extremely complicated butt and marking gage with lots of reference faces and points. It could allow fixed or adjustable gain, allowed points to be extended as they were sharpened, and supposedly solved the problem of the gage "tipping" as it marked. One of these appeared on a Patrick Leach tool list.
