I just have hard time believing that a Purdey engineer would not get the grain right. The forming to that shape could easily done when hot and the first outward bends of the ears done in a pressbrake, the center bend started in the pressbrake, then closed by pinching the outside in the pressbrake. All done while hot, probably in less than a minute. I just don't see any reason to use machining or wire EDM to make that raw part. If they sawed it or used wire EDM, they sure lost me on the logic. But there's always a bunch of ways to make something.
