I just bought a 1898 krag carbine, it has the "C" markings on the rear sight, and it's serial number 1215xx. The stock has the 1900 stamp on it, it had sling swivels and a 1907 on it that I took off. The barrel also appers to have the proper front sight, and is 22" long. I don't know a lot about these so I would like an expert to weigh in. Also, let me know if anymore pictures are needed
