Impossible to answer
Winchester did not make a Model 1863 rifle. They made a Model 1873, which was chambered in .32WCF. Would need a LOT more information to answer this question. sales@countrygunsmith.net
You will have to pay 3,000 dollars or more for a original Winchester model 1873 lever action Winchester rifle in the condition you described.
Your Winchester model 1873 rifle was made by Winchester in 1904,with the serial number that you provided.
I can't get any serial number search on the 1873 to work if I put a letter in it. If the number is 336132, the gun was made in 1890.
Your Winchester model 1873 rifle which was made in the year 1900 could bring anywhere from 800-4,000 dollars,depending on overall condition,any special order features,and the bores condition.I would advise you to have a member of the Winchester collectors assoc evaluate your rifle/carbine for a much more accurate value.
Winchester made the model 1873 rifle and the model 1876 rifle,but did not make a model 1875 rifle.
