Nice buy. Very nice. 28" bbls on a single bbl 28ga seem to be a rarity. I hadn't seen another since I bought mine a couple yrs ago. And the double triggers on yours are now highly sought after. I'm sure Tom Skeuse would be scratching his head over that.
I got very lucky with the gun I found a couple yrs ago. It has nice grain orientation in the wrist and a great feather in the butt.
