Thanks to replies to my post last night. I knew when I posted my topic last night that the members are probably tired of hearing about 1898 carbines that aren't carbines. After looking at the photo's on your site I see that my rear site is probably a 1896 and not an 1898, and that is disappointing.
My serial # is: 133933 and the barrel length is 22 inches. The stock has a cartouche that has 1898 and three initials on it, also has a fancy P in a circle below the trigger guard.
