if the one you have says it was made at "Ludwig Loewe & CO in Berlin", then it was surely made by 1896, because in 1896, Loewe and the Mauser brothers combined to form DWM. So if your rifle is marked "DEUTSCHE WAFFEN - UND MUNITIONSFABRIKEN, BERLIN", it was made in or after 1896 (as in, it could be after 1898).
