There is a recent reddit post about a sword like this, thought it might help you. https://www.reddit.com/r/SWORDS/comments/hl0yjn/found_in_south_africa_does_anyone_know_what_this/

Although the provided image is a bit unclear, I believe that the inscription is the same as on another image which I gave a quick-and-dirty translation on /r/translator a while back. Here is the inscription in the question (left) and the one I saw before (right), side-by-side:
隹(唯)周父王亖(四)秂(年)𠄡(五)月𠆦(作)豆𤰃(用)亯(享)于宗室
The characters mostly have shapes adhering to bronze inscriptions. The rough translation is
The dòu (豆, round-bottomed bronze vessel) was cast (作) by the Father (父王) of the King of Zhou (周王) on the fifth month (五月) of the fourth year (四年) for (用) recreation (享) at (于) the ancestral temple (宗室)
Personally, I thought there were some problems with the character shapes and the language used in this inscription, which made me doubt its authenticity.
隹周父王亖秂𠄡月𠆦豆𤰃亯于宗室
There is an item with this inscription which appears on a Taiwan auction bidding site. I can't gauge its authenticity, but there is a long and supposedly historical background of the object given at the bottom of the auction page, relying on an erroneous transcription of 「豆」 as 「亶」.
