I've got one really nice condition Springfield Trapdoor rifle that I bought to compliment my interest in and collection of Krags. I learned about it and bought nice black powder ammo to shoot in it and it was fun.

But, I am mostly fascinated in how closely they are to the subsequent Krag design because of such similarity of features.

Your carbine shows off many of those features that Springfield Armory continued in the Krag design.

Thanks for sharing!
