I left out the part of where I was looking for advice on what is original and what is modified (sporterized)

Howdy Thelfter, and welcome to the forum... and to the wonderful world of Krags!

Looks like an 1898 rifle that has been sporterized.  You have an 1896 rear sight, although the leaf has been flipped all the way back, and should be flipped back towards the muzzle.  The stock has been cut down and sanded to make it more manageable for hunting.  Likewise, the barrel appears to have been cut down from the original 30 inch length.  Can't see the front sight post well enough to see if it's the Krag post that's been reattached, or an aftermarket post.  The handguard is missing.  How does the bore look?  Hopefully, it's not full of rust and pitting after sitting for 50 years.  If the bore is ok, then it should be a fun shooter!

'thelfter' - Welcome to the KCA Forum. I'm glad you inherited the 'Family Krag'.

Clear detailed pictures of your Krag's front-sight and barrel muzzle would be helpful in determining your Krag's 'origin'.

Serial #127280 is in a 'block' of numbers that were used by both model 1898 rifles and carbines.

A picture of the 'numbered side' of your rear-sight's leaf and the tip of your wood forearm would also be helpful.

Your Stock has been much sanded, but, the length of the 'finger grooves' and the far rear position of the barrel-band, suggest, it could be a type of model 1898 carbine stock. (From the period when the carbine sling-bar & ring were eliminated).

Such a stock would show an area, on the right-side of the tip, where a band-spring use to reside.

Your Krag now has a rifle barrel-band that clamps into place. The "U" on the barrel-band should be on the right side of the Arm.

Your Krag also has a rifle Butt-Swivel, which normally is not found on a carbine.

Good information all,   Sorry the pictures are blurry -- I had to drastically reduce them in order to hit this sites file size limits.

Grabbing photos of the stock and rear sights.

No Flat Spring on the stock

Your rear-sight is the Rifle version of the model 1896 sight.

Your barrel-band is on backwards.

Your stock is perplexing, because the 'finger grooves' do not appear to be the length found on Krag rifle stocks.

When you take your Krag apart, please photograph the stock barrel-channel.

I am curious about your barrel's length.

Please measure the length of your stock's 'finger grooves'.

On Krag rifle stocks, the grooves are about 6 and 1/2 inches long.

'thelfter' - I can't tell what your Krag was altered from with just the pictures supplied.

A real carbine barrel would only measure 21 and 1/4 inches at the points you have used (not 22").

Your stock has been thinned and reshaped in some areas. The finger grooves are shorter than those of a Krag rifle stock and the later (model 1899) carbine stock.

IMHO - It would take an experienced Krag person, examining subtle details first hand, to figure if there is part of a model 1898 carbine contained in your 'sporter'.
