I guess it would have to be understood by all that this would be a serial number/receiver census.  We all know Krags range from pristine full military to Dear Lord What Happened To It.

Keeping it simple is the way to go. The line of questioning for me would be this example.

I saw a Krag today.  It had Model 1898 serial number 127000 on the receiver, 24 inch barrel, and a M1903 front sight.

127000  M1898R 2019 07 26  Cut down rifle or left blank.

I saw a Krag today.  It had Model 1898 serial number 198000 on the receiver, 22 inch barrel, carbine stock and a M1901 rear carbine sight.

198000  M1898C 2019 07 25  Proper carbine or left blank.

Of course we can still post in the forum if there is a question on a particular gun and get opinions on what it is as we always do.
