The Hunter Arms Company choked all their double guns full and full unless otherwise specified by the customer; so tight choked Smith guns certainly aren't a rarity, and I suspect most period American double gun makers had the same policy. In the tight coverts of N. Georgia a full choked gun would be a disadvantage; although not so much for dove shooting. I once owned a late (1904) vintage 12-bore Syracuse Arms 30" Damascus gun choked improved cylinder and full; it was a marvelous gun for dove shooting, and if the wind wasn't blowing I could actually hear the shot charge from the full choked barrel smack a dove when connecting on a long range shot. But the longest shot I ever made was at better than 75 yards on a running cottontail using a 20-bore Parker whose right barrel was cylinder bore. Two witnesses were astounded with the shot, which was pure dumb luck, but the autopsy revealed just one #6 pellet in a sweet spot. Personally I've killed lots of game using cylinder bore guns and don't feel the least bit handicapped using an open choke where I've hunted, but I've never hunted the wide open plains and wild pheasants either; had I done so I'm sure I'd have an entirely different opinion.
