Can't make out the serial # to see if the 1902 cartouche is correct. But it's as original as can be otherwise. You've got eight choice for which state it served in National Guard with:
Maine
Maryland
Massachusetts
Michigan
Minnesota
Mississippi
Missouri
Montana

Not all marked their rifles, but I think Michigan was in the habit of doing so. Even if the serial # doesn't come up as produced in 1902, swapping stocks was a common thing. Many rifles are in stocks cartouched with a year other than than that of their production. That is a nice one, the wood was referred to as Italianicon walnut. I have a Japaneseicon type I rifle, which was made by the Italians for Japan, and the wood is the same color.
