Hi Arizona Travis,

I have an 1899 carbine that was also dove tailed to allow for the Marbles sight mounted on the rifle when I purchased it.

Fortunately for me the original Krag rear sight holes were not filled-in and I was able to easily restore to its original 1899 configuration.

Your grandfather's Krag has a neat history and I would leave it as is with the exception of trying to stabilize the crack where the screw is on the left side.

Additionally, if you choose to do so, Marbles or Marbles like buckhorn sights are easily available on the web.

You can also fill-in the scope holes with set screws you may have laying around or you can acquire them from a gunsmith or hardware store.

Otherwise, trying to restore it to original condition would be a costly endeavor!

BTW: I think the front sight is kinda cool!
