32" Duck's are very nice for the blind but they were standard with 13&5/8" LOP and pistol grip, which was one of the smartest things Winchester ever did as this makes them very comfortable and easy to control for cold weather use. A 1950 Winchester catalog does say it was a $4.60 option for straight grip but lists no LOP. In any event the gun should be marked 'Duck' on the floorplate and I would get a Cody letter stating the gun was originally sold as a Duck before purchase. In any event, Duck chokes are usually about 35 thousands. With Kent TM #1 shot, 50 yd goose kills are very possible but I would not purchase one and modify the chokes. They were made for waterfowl hunting.-Dick
