Here I have a shell from feb 1899. It’s large and would love to know more about the marks on the base. I have looked up on the internet but being new to this scene I’m struggling. I would much appreciate and help.
As you can see there are a few different marks,
FEBR 1889, Kalrth with a number 12 under that, and a symbol under that of which i have no idea what it represents, P47 near the center and some marks on the centre bit.
Thank you in advance of any help you all can give.
