Well, the markings really says it all.
Like the Sheffield Bowies exported to America (and then into Mexico), there was a huge influx of knives from Europe to South America - for example Argentina.
The designs of knives in North America was at some point influenced by designs from the South.
Knives were also made in the countries mentioned.
The very elegantly flowing design of your knife makes it very Mexican in looks apart from the markings.
Nice looking knife, I like it.
