Andhar, they are all different designs as Paul Mauser worked out the details. The 1871 is a very different rifle from the 1898 and I think it would be a whole lot of fun to have shootable rifles of the whole sequence from 1871 to 1948 (the Yugo which was the last one in production). There are a couple of duplications but that's because the given rifle (1908 Brazilian, forex) is a nice version. Except the 1916 - I just want one as a 7.62x51 trunk rifle.
