Welcome indeed!

Unfortunately, you have picked the "worst" possible model to restore. To make it "as made" (a Model 1892 Rifle - there were only TWO carbines made and both are accounted for) would take thousands of dollars. To emulate a M1892 Rifle brought up to M1896 specs - as most eventually wound up - would still take many hundreds of dollars.

If you want an "original" full-length Krag, I would look for an M1898, or even M1896 Rifle. There are always several nice ones to choose from on   (You need to Login and numerous people here would be glad to vet any prospective purchase for you. Sadly, you bought first and asked your questions later. You will probably find your new baby hard to sell - but my recommendation would be to do just that and acquire one for which you do not need to make excuses. Will the shop take it back? My guess is that they were extremely happy to find a buyer for something which would not have been a fast mover.

Or, if finances permit having two Krags - keep this one for shooting/hunting/general fun, and get another for the historical aspect.

Don't mean to be harsh, at all - just my $.02 after 45 years of Krag collecting!
