You and I have the same Reproduction set...Very few of them got out....
As far as original Parkers and the 16 Gauge; while some were made on the 20Gauge frame, others were also made on a larger frame.
I've only hunted with it once but I have no plans of getting rid of it and hope to use it a lot more. I wish it was IC/Mod but it's skeet and skeet.
