Gentlemen, Did "WE" view the serial# when looking at the gun? There is only 1 Purdey with that Sr.#. I might suggest that a"Serious Punter",(Before writing the cheque for the gun)hire the services of a "Qualified Gunsmith" to have a Cerrosafe' casting made of each of the chambers,and go forward of the forceing-cone at least 1/2" into the bore. To use a "Quote" from a old Purdey Barrel-Maker,"Its easy to remove steel from a Barrel, or a chamber but much harder to put it back in" !! C/C
