Ken:  I hope I am not coming across as arrogant or a 'know it all'.  I am curious where you obtained your 'Krag' tool.  I believe there are a number of things wrong with it.  I have seen original tools that were assembled incorrectly by Springfield with the pin drift pointing the wrong way.  But, your tool seems to have an odd looking "US" to me.  Your screwdriver tips appear 're-ground' and the 'pin-drift' is too long and looks new.  You should look at the hinge end of the tool for evidence of a third screwdriver being ground-off.  I am attaching a picture of an 1897 Krag tool next to an early 1903 Springfield tool.  The 1903 tools were made for 40 years, through WW2, by private makers, as well as, Springfield.  I hope you do not have too much invested in your tool.  Real 1897 tools are often priced around $90.
