I could go that route I guess, but I figured that you guys might know too. Do those letters come direct through Winchester or do they come from the Cody Firearms Museum? Actually the rifle belonged to my step dad's father, so it does not have any sentimental value to me there as they are both gone now. I don't think that a .25-20 is very useful as a cartridge to begin with. Oh it is fun to shoot, but then lots of rifles are.
I was just looking around on the Internet and it seems that what I have might be a 1892 Sporting Rifle. By the serial number it looks like it was made in 1905. The barrel length when measured from the back of the barrel with the action open is now 22 1/2". There is no saddle ring and the magazine tube is 1/4" short of the barrel end. There is no full around the barrel band, just the magazine pinned on to the bottom of the barrel. Do you think what I have is all original?
No, if I'm visualizing what you're describing correctly, your rifle originally had a longer barrel that has been cut off. All sporting rifles would have the magazine hanger. Your rifle was probably a 26 inch barrel gun and the barrel was probably cut just in front of where the magazine hanger would have been. If you carefully examine the underside of the barrel, there might be some sign of where the hanger used to be.
The letter info comes from the Cody Firearms Museum. Unless there is something special about the gun, I don't know that I would invest in a letter. But, if you know anyone that is a member or the Museum, they can request the info and receive it in a fax or email.
