If you look futher down the album there is a forend made from what seems a combination of subtactive technologies- EDM wire eroding and CNC machining, a combination I find rather clever.
The shock to some that bespoke guns utilise these technologies is understandable. But may be we should not confuse the product with the way it is made.
I still have my spring bending jig somewhere. Making and tempering a spring was a big deal. Then I found OMPS in Italy and got V springs semi finished. Nothing makes you like coil springs faster than making your own V springs. That big chunky "motherblock" for V springs in the pic shows that even the best makers have a hard time with V springs and try to solve the problem in innovative ways.
