Interesting rifle, would be nice to know the history. It's doubtful they will be able to tell you anything other than when it was made. I had a letter done for my '20s vintage 1895 and that's all they had. My 1885 made in 1887, they were able to tell me how it was originally configured and when it was received and shipped from the warehouse but nothing about where it went.
From the Cody website:
"Winchesters after 1906
Most Winchester records for firearms manufactured after 1906 to the end of the surviving records only contain dates of manufacture. These date-of-manufacture records are called Serial Number Application (SNA) records. SNA records are available for many of the earlier Winchesters and are automatically included in those serial number searches and factory letters."
