'Marksc' - Welcome to the KCA Forum.

I think the logical answer is that someone (God knows why?) removed the serial number from your Krag's receiver. It should be where there is a vague 'cross like' shadow area on your receiver.

Your nice carbine stock is the later type (1899) 'long forearm' stock. These often were used as replacements, during refurbishment or repair of model 1898 carbines, to make them identical to the model 1899 carbine.

Is there a cartouche mark or 'proof P' stamp on your stock?

Is your model 1896 rear-sight a rifle or carbine sight?

Your side-plate screw appears overly long and your magazine cut-off lever is missing. This suggests to me that someone had a Redfield 'no-drill' peep-sight (102-K or 70-K) on this carbine for 'Hunting', at some time.
