OOps, in case you do not know, the water table is the flat part of the gun frame ahead of the mechanism onto which the barrels flats hook into and lay flat on. Bad grammar, anyone else want a go at explaining water-table? Proof marks for the action as stamped on the water table. No, I do not know why it is called that, it's a British term, they always called it that, so get used to it.
