Seeking help to identify a blade!

[MeleeTiger]

I purchased this old blade from my local pawn shop some years back and have been trying to get an idea of where it's from ever since,
I believe he said that it was brought back here by a soldier who had been stationed in Africa but that's kind of a vague deal when you consider on big and varied the country is.
I came here to this community after some more searching and thought that just maybe I'd find someone who could give
me a better idea of where it's from and before anyone asks, no I'm not looking to sell it or any other piece of my collection but I would like some peace of mind relating to it's origins.
These photos were taken not long after I purchased the item, if they're not
any good for getting an understanding of the piece I can take some new ones
to try and get a better image of it for identification purposes.
It's clearly hand forged if the tang is anything to go by but has no edge so
I'm thinking it was more decorative or ceremonial in design rather than function?
