Odd early .303 marked shell I can’t figure out

Hey guys,
I was lucky enough to gain entry to a very old race coarse (1880’s) to have a metal detect on here in Western Australia. This area has a rich ww1 and ww2 history. I found a few .303 shells and this ones got me stumped . Anyone know more about this old one? Any help is muchly appreciated
