1903 supposedly from the Philippines in a case with a plaque?

[John Beard]

If your rifle was brought back into the U.S. in modern times, then it would have passed through an importer such as Century Arms or Blue Sky. And the importers were required to place their marking somewhere on the rifle so that it could be traced by the BATFE. If you encounter such a marking, then that should enable you to learn more about your rifle's history.

Good Luck!
