So if the proof marks are on the barrel ,not on the flats ,that becomes the water table in American parlance?
By the by I believe "the pavement " is what the former colonials call the road they call the pavement a "side walk".
For Americans, if the proofmarks are on the barrels themselves, they're on the barrels. (We believe in keeping things simple.) What we call the water table you Brits call the action flats.
Pavement isn't quite so simple, because while it can refer to the road itself, it can also refer to the material of which the road is constructed. Thus, although sidewalks are typically paved, we'd never refer to the sidewalk itself as "the pavement". Rather, sidewalk is a perfectly logical term. It's a path, usually beside a road, designed for walking.
