Someone will be along very soon to tell you how you don't really need any choke with today's modern shotshells. But it won't be me. If you have enough "meat" near the muzzles you can get some choke by jug choking, but not a large amount, usually. You can have a permanent choke tube soldered into the barrel, but it requires machining and a very capable smith. There will be a faint line showing at the muzzle but nothing else would be visible, if done right.
I have a 32" BE 1919 Fox that was for sale with Briley S1 series thin wall screw-ins. Very few people have ever noticed them. Not sure how they would affect the value of a double that has had the barrels already cut. If I were interested I'd much rather have a double with screw-in chokes than one with no choke at all in both barrels, so it would not degrade the value in my eyes. Others will probably disagree.
