I am far from an expert on Krags but I can find no reference to a 1894 Krag carbine in any of my books. Blue Book of Gun Values thirtieth edition lists a 1892 Krag dated 1894 but thats a rifle and they say only 2 1892 carbines are known to exist. They also mention a 1892 Cadet Rifle but its almost as rare as the carbine. Then they move on to 1895 and 1896 rifles and carbines. The 6th edition of the Standard Catalog of Military Firearms pretty much agrees but only list the 1892 in rifle form under United States military firearms. Under Norway they do list a 1894 Krag but only in rifle form. The first carbine they list is the 1895. As I said I don't really know much about Krags but just wanted to share what my books say. I'm sure someone here will jump in that has more knowledge than I.

"Of all tyrannies, a tyranny sincerely exercised for the good of its victims may be the most oppressive. It would be better to live under robber barons than under omnipotent moral busybodies. The robber baron's cruelty may sometimes sleep, his cupidity may at some point be satiated; but those who torment us for our own good will torment us without end for they do so with the approval of their own conscience." C.S. Lewis
