Ken:  I'm not aware of reproduction 1897 tools.  Unfortunately, it would not be hard to make a fake from the more common 1903 tools, especially early ones.  My Krag tool is marked "US" (no periods) and my early 1903 tool is marked "U.S." (with periods) and the same style of letters.  By the way, I learn something new every day.  Answering questions sure makes me see things in a new light.
