I trying to figure out a Winchester semiautomatic 12 ga. shotgun that is factory stamped Model 1200. The gun was built by Winchester for an 1980 Olympic tryout trap shooter, Steven Hager. I have an email picture of it which I don't know how to post . I can email it to anyone if they can help. I can't find a listing anywhere showing a 1200 semiautomatic trap gun. As far as I know 1200's were pumps. I know the gun was made before 1977. My brother works with Steve and he has the gun in Va. In the picture the gun looks like a 1400. I'm buying the gun. I just not sure what it is. Thanks.
