Re: It's a hand hole, isn't it?
But was the escape made to fit the hole or was the hole made to fit the escape? The shape would be a simple one to make with common tools. drill two holes of proper diameter and then cut a straight line from one hole to the next. It does not make nearly as much since to design an escape to such a shape. For this reason I suspect the hole was already present and the escape was designed to fit it.
