Q1 & Q2 choke constrictions

[Woodcock survey]

My 20 Repo q1/q2 is right 3 thou, left 7 thou. Hunting grouse and woodcock the first shot is usually closer so the front trigger is naturally the one you come to first. I started hunting with double trigger guns 60 years ago and have developed the ability to judge the distance and reach the right trigger with out thinking about it.
On the skeet field outgoing back trigger incoming front trigger. The constriction is perfect with todays plastic shot collar shells. Back when Parker made the skeet guns the ammo needed bit more choke to accomplish the same pattern.
Today with our guns and the current ammo we are ,in my opinion, over choked for most of are shooting. Some very long hits can be done with a modern load in a full choke Parker once you have figured out the lead at those distances

The below brochure introducing the 28ga. Parker Reproduction to the marketplace is not shown on the "The Parker Reproduction Literature" page of the "All Albums" section of this website; but, it ought to be! This one-piece brochure (with dealers listed on the back side) is not dated, but it is thought to be from 1986. If 1986 is indeed correct of when the 28 ga. Repro was first introduced the Q1/Q2 offering appears to answer the question of which choke stampings came first -- Q1/Q2 or Skeet1/Skeet 2.

But, of course, when speaking of Parkers, we never say never.
