Now there is something strange with that rifle. All "African" -type factory made Mausers, even the older ones like my rifle is, do not have any shotgun type trigger guard. These older ones have solid trigger guard magazine with bottom lever and the later ones Mauser Argentine -type trigger bow with magazine.
I don´t know if the owner has modified the stocks butt end but in my eyes it doesn´t look like it should be if it´s outfit is the original one.
