The sears model 200 is a Winchester 1200. That will make it easier to find info. I have one of these, with adjustable choke and vent rib. It is a sweet shooting and smooth little shotgun.
With the serial number that you provided,your winchester model 1912 pump action shotgun was made in the year 1959.There were 104,672 made during that year.
As for the age of your Winchester model 1912 pump action shotgun.It was made in the year 1961.As to the value,that would be based on the amount of original finish remaining,and a good bore.Without that info supplied I would not be able to ascertain a distinct value for your Winchester shotgun.
12 gauge winchester 1900 made in 1899.In order to assist you in defining a value to your Winchester shotgun I will need to clarify some info provided and ask that you give a more detailed description of the shotgun in question.First I will say that Winchester made the model 1897 pump action shotgun,they made a model 1901 lever action shotgun in 10 gauge only.They also made the model 1911 semi-auto shotgun.So you must determine the model of your shotgun first.Then provide more info on the overall condition of the shotgun to include the amount of original finish remaining on the wood and metal,type of barrel(plain,vent rib,solid matte rib).All these things will help me assign a more accurate value to your shotgun.
Your winchester model 42 is a highly collectable shotgun,and if yours has a original finish remaining of between 60%-95% will bring between 1,200-2,000 dollars.This is for a standard grade model 42.If you have the skeet grade then the value will be between 3,250-5,500 dollars.If yours is the trap grade shotgun ,then it will range in price from 8,000-13,000 dollars.Your serial number indicates that your Winchester model 42 shotgun was made in the year 1953.I hope that you find this info informative.
