I have a very doggy 96 carbine I have owned since 1974. It came with a bullet lodged in the throat... Probably a rimmed pistol cartridge someone tried. Being a shooter and somewhat collector but mostly a shooter, I lack expertise on the finer points of collecting and I admit it. My rifle has no saddle ring. Is that in itself a problem? There is a "c" on the carbine sight.
You would not approve of what I did with it. The bore was so poor I never could get it to shoot in spite of "every trick in the book" that I have used in the past on bad bores. I put one of those horrible Numrich carbine barrels on it with the mis-drilled rear sight holes. Now it shoots very well but it is no longer original. I do have the original barrel and sight, of course. Had to put a 1902 sight on it to get enough Windage to get it on paper, and the hndguard won't fit... I'll look and see if I can't add my SN to this post.
