Classic Doubles was the same gun renamed starting about 87'- until about 92'.
There was a 201 Waterfowl Model

There is no one to ask at Winchester nor at Guns International in Omaha who bought remaining inventory about 90'.

With those chokes I would, but I'd avoid today's waterfowl hyperspeed boomer loads.
