Gun #177 with two barrel set and gun #321 I checked personally got no visible chokes, but difference between diameters in 22 cm from breech and at muzzle were from 0.1 till 0.25 mm.
At the same time all 3 barrels I checked show pattern much more tight, than I expected, by most tight pattern it looked like barrels had modified choke, but only with particular shot numbers.
But long 34" geese-swan barrels show allmost full choke pattern, when shooting 3/0!
There is something I can't explain, but have read the same about old gun makers such as Mortimer, his cylinders shot as barrels with 1/2 chokes.
