Let me set this up. I have some experience with Ithaca trap guns. The typical Ithaca choke starts in earnest about 2 inches from the muzzle and finishes with no parallel. It's a dead giveaway for a factory choke, seemingly regardless of constriction (remember, these are trap guns I'm speaking of, not field guns or open chokes).

Of the four or five Parker doubles I have, nothing about the chokes jumps out at me as being anything out of the ordinary. My SC trap, however, has a long, slow choke that begins about six inches from the muzzle, starts to get warm with about 2.5 inches to go, and finishes with a half inch of parallel. So, the question is, have any of you arrived at a point where you think there is a house signature choke profile for Parker's singe trap guns?
