Winchester 1873 s/n 66557 was manufactured in 1881. The condition and verification should be done by an expert. I understand that the Cody Museum can provide a letter as to the factory shipped configuration of the rifle and, as there were many factory options available on that rifle, a professional apprasial should be considered. Depending on condition and options, the rifle can run to $9500 and the carbine to $12000.

The Winchester 25-20 caliber was first chambered in the Winchester model 1892 rifle/carbine which was made from 1892.The last chambering that I have found was in the Winchester model 43 bolt action rifle that was produced from 1949-1957.I would surmise that this caliber was available from 1892-1957.
