craggy joe:  Welcome to the Forum!  You have a Model 1896 Krag Rifle that was shortened and turned into a nice 'Sporter' a long time ago.  The rear sight is a Lyman No. 34 (worth about $150).  The front sight is a replacement band type of economy quality.  Your barrel is anchored with a nice barrel-band, a good feature.  I can't tell if your stock was 'new' or a recycled military stock.  The butt-plate is a commercial Neidner style.  The whole rig is probably worth $300 to $450.  Enjoy!
