Please say more about why you do not regard the Hussey Imperial as the equal of a Purdey? If the Hussy has the diamond grip and the rest of the "Imperial" traits, that is probably not the conclusion a majority would reach. Barrels are the main value component of a gun; both have issues as presented by you. It would seem the Purdey has slightly more though in that the open chokes and pitting cannot be put right while maintaining the value of the gun.
