A -3 would very likely not be a new-production piece. Inventory of those frames and other parts is long since depleted. If I were a betting man, I would wager that it is a 686-3 Classic Hunter with a Combat stock. It has Classic Hunter equipment - a black ramp front sight and unfluted cylinder - and it is a -3, which they were. If I were at my office PC, I could post a photo of my 686 Classic Hunter and the stocks would be the sole visible difference. Anyone else with one can do the same.

I'd love to see the box label.
