In reading the definition of fences on the Hallowell site, it appears that calling the "breach balls" "fences" is a complete misnomer as there are no "fences" on the "breach balls" of a hammerless gun, yet there are indeed "breach balls or equivalent on a cap hammergun.
The term "watertable" has been used also in many things other than guns and building architecture. In the machining and fabrication world, as well as airplane manufacture, the term "watertable" is often used to describe a flat surface (sometimes related to a "waterline") as a datum reference that provides a relative angular and dimensional reference for location of other features or components.
