what does 120A choke mean-- I have no idea what you are talking about with this question about a choke
It sounds like to me that you have the Winchester model 1200 police stainless model.The serial number just means the number assigned to your shotgun during the time of production,nothing more.The Winchester model 1200 series shotguns were produced from 1964-1981.The serial number was mandated by the goverment with the passage of the gun control act of 1968.
