It looks spanish, or spanish influenced in the design.
The major problem with this type of ‘primitive’ design is that it could be very old, or it could have been made yesterday in South America using primitive tools and to an old design. It looks to be damaged / incomplete, there should be a pin, or guide in the keyhole that the key would have revolved upon. I assume you have no key ?
So, it maybe very old ie, 200 years +, then again it may not.
Who made it - absolutely no way of telling.
