Gnomon,
I think The Field article that you are referring to is about a Boxall & Edmiston gun.
These are superb guns manufactured using CadCam & CNC but then hand finished and assembled by some of Britain's finest artisans. Ex-Purdey, Ex- Holland & Holland employees now self employed, and dedicated to producing 'Best'.
A number have all ready been made and snapped up by the mysterious 'collectors' perhaps never to see the light of day for a good many years. But there are an increasing number of them beginning to appear in the field. They appear to be very functional & reliable. So much so that I hear talk that they are considering offering a lifetime guarantee. You will only have to pay for repairs to guns that have been damaged or worn out with fair wear and tear.
A very brave venture but testimony to the build quality.
