IMO the PolyChoke is an aftermarket addition on that particular Winchester because, AFAIK, guns/barrels with factory-installed compensators were usually Cutts, but even if a PolyChoke was used, no choke designation (CYL) would have been stamped into the bbl.
Soooooo, removing the PolyChoke & re-installing the proper bead front sight should restore it to the way it left the factory (provided the bbl hasn't been shortened, etc) - a cylinder-choked shotgun.
