JoeA:  Right Click on the "Visit the KCA Website today" when the banner appears at the top of the forum page.  This will take you to the Main Page.  If you then select 'photos' and scroll down the photo page, you will see photos of different model Krag sights and handguards.  This will probably allow you to identify what you have.  I'm thinking you might have an 1898/1902 style handguard.
