Thank you to everybody who weighed in. I will fire it next week. I expect the case to be normal Krag. Someone went to considerable lengths to modify this: pistol grip added, ramp front sight. Excellent forearm and 1902 rear sight. I forgot to mention that it had a forearm screw that went into a vertical stud on the underside of the barrel. I will take it to the July Missouri Valley show in Kansas City to see if there are any "old Krag hands" there who can shed any additional light.
