Brass shell cases x 2 Questions

[monochrome]

I have 2 shell cases that i think i have worked out what they are but was hoping for additional comments or comfirmations.
Both are Broadarrow marked, one is from the Australian Navy 1950s a 4.5 inch Mark 3.5 case
and the other is a Boer War era (1900?) case i think but i don't know what gun its from, any ideas based on the photos anyone?

The first is a British case made by E.Curran & Co. (ECC), South Wales. The primer was filled at ROF Chorley in April 1963.

The second is "EOC", not "BOC" and was made by Elswick Ordnance Co., later part of Vickers.

It is not my area of knowledge but a guess is it looks like a 3 Pr. Nordenfelt. Loaded once with cordite full charge on 28 february 1900.
