You're right Dean, I just went and re-read that in TPS. I had it wrong as I thought the SK marked guns came first, but it was reported in TPS that the Q1/Q2 choke designation appeared first in 1986 to appeal to quail hunters and then changed to SKI/SKII in 1988. I have to believe that the SKI/SKII marked guns are few and far between, as I cannot recall seeing one first hand--but then I'm getting old.
