Someone recently said that France possess (collectors in France) great German rifles, which we have known for a long time, but this rifle is just another good example. Any MO (WMO) 1899-1905 is rare, they made relatively few until 1906, and 1902 is one of the toughest to find. Near impossible to find totally original, and this one probably is original, - at least I didn't notice any replaced parts.
Another exceptional rifle today, very rare this early. Hope it hasn't been demilitarized and you can keep it safe!
