Gene,

If £3,500 was the hammer price it has cost the purchaser £4,550 to get it out of the room.

He (or she?) can no doubt afford to get some Black Powder 2” .410 cartridges loaded, but with a 3/8 oz. Shot load will be restricted to very short ranges.

At that price, he would have to be very very brave to risk having it re-chambered to 2 1/2 inch or 3 inch nitro and risk the Proof House rendering it valueless.
