'Aitrus' - Welcome to the KCA Forum. It is neat that you have a 'sportered' Krag that is connected to your father and father-in-law.
(Kind of incestuous)!

It is likely that your Krag, #247385, was assembled around January, 1900, as an infantry rifle, with a 30 inch barrel.
(By this time period, Model 1899 carbines were being manufactured, and were stamped "Model 1899").

Your stock is a "cut-down" rifle stock with an added-on pistol grip.

Your rear open-sight was made by William's Gun-sight Company, (Davison, Michigan). There are a couple of tapped holes on your receiver, in front of the bolt-handle, likely once holding an aftermarket Lyman or Redfield 'peep'-sight.

Your 'banded' front-sight looks like a Redfield or Lyman product.

Your Krag was obviously "cut-down" to make it handy for Hunting.

It is still great for that purpose and a Family Heirloom to boot!
