Gerald's post reminded me that I also have a vintage, very collectable, gun that has been screw choked. It is a restocked 1918 BE grade 32" Fox. It was advertised as such, so I knew what I was getting into. It has the Briley S1 series thin walls. I already had "accumulated" a pile of them for a Perazzi (won two $500 Briley gift certificates at a big shoot once) and for an Italian hammer gun, so multiple sets of every constriction. It has served me well on doves and ducks.
I guess the ultimate test is to ask yourself would you by a nice vintage gun with screw chokes. I'd have to say the answer for me is yes, because the price was right. Downside? The prices were reduced, which means the market devalues them. Sometimes "it don't matter".
