Hello, I came across a full length Krag Model 1898, serial number 224488. The buttstock is stamped in large letters/numbers "5th" and underneath that is "34" and underneath that is "M". Everything functions, fires, and ejects. Now the really interesting part is that the full length barrel is solid and never was rifled. Also, the bolt face where the firing pin exits is brazed over with brass.....Has anyone ever seen anything like this ? Thanks for your help.
