You made a wise choice for your intended use. My favorite in my collection is an 0E 20 with 28" tubes choked IC/M used for doves, quail, grouse, woodcock, and gets a workout on skeet and sporting clays. From the picture yours looks like a non-selective single trigger---- uncommon !
As to your question--- I'll be the first. Judging from the abundance of the blue and the relative lack of orange in the colors, and the faded appearance of the blue on the forend my guess is a recase--- nice, but not factory.
