Bushveld, my gun is like the plate 29 in Dallas's book, but standard engraving. Mine is #20,300, a bar in iron gun. I emailed Purdey more than once, asking about my gun but never got a reply. Palunc, is your gun a hammer gun? At 7 pounds, 12 ounces yours is surely a pigeon gun, My gun has a very narrow file cut rib, not the classic pigeon rib, but I guess that was the owner's choice. You are right about luck. As luck would have it, I am a pigeon shooter, box birds and Columbaire, have shot a bit of helice, have a good collection of Parker pigeon guns, when the Purdey fell into my lap. The gun store was just a few miles from my house and I had only been in there a couple of times.
