Berretta choke tubes

[Larryjk]

Goody, Stand the chokes side-by-side and line them up in increasing number of notches on the leading edge. You will see that the one without any notches is the full and down in descending order to imp. cyl. that, if I remember without looking at my chokes,that has four notches. The more notches, the more open the choke.
