Ready for it? It's an 1899.   ;D The receiver, if you remove the scope, likely has "Model 1899" and started life as a carbine.  Not that it matters as it's drilled and tapped.

That's why I love this forum... because there is never a shortage of knowledge.  I knew that someone would know better  based on the serial number.  As I frequently say, I'm no expert  :D 

If it started as a carbine, why the replacement front sight???  Hmmmmmm  As Arte Johnson would say:  Very Interesting!
