i just looked at a perfect candidate: 7.5lbs 30" Krupp Laufstahl barrels 3/4-full combo with flat rib. this is what experts call transition piece with heavier scroll engraving and no barrel weight number (those were made ca. 1912-1913). total production in this configuration was less then 400 pieces. well worth it's $3500 asking price. the barrels were made from same steel as 38cm main barrery of Bismarck/Tirpitz class battleships.
i advise for you to forget that overpirced english stuff. just remember who won the battle of the denmark strait.

fast flying pigeon much like high pheasant requires 30-32gm #6 or #7 load with mv of about 1350f/s.
oh yeh there were couple of birdies in flight engraved just ahead of trigger plate screw. not sure what they were supposed to be but perhaps they were woodpigeons the only pigeons worth shooting at.

the usual weapon of european shooter is 12br browning or beretta o/u shotgun.
PS. to read more about this fascinating sport please refer to the woodpigeon the ultimate quarry by paul smith and peter thobald.
