I recently purchased the above referenced gun. From what I was told, the gun was sold in 1981 at Vandalia. It is a fixed choked gun, and shoots very well. Supposedly the chamber and trigger were improved, and the barrel ported by a master gunsmith named Miller. I’m wondering who Mr. Miller was and was he in fact a master gunsmith. I think he honed the chamber and smoothed out the trigger. I’m wondering if that was standard practice back then.
