Hey bro, it is brazilian indeed. Very similar to my father in law set, posted here a couple of months ago. The set was bought in Sao Paulo some decades ago. So far, I couldn’t identify the maker.

I bought this antique chess set here in Brazil. The seller said it's about 50 years old and I believe that, but I don't think it's brazilian made. It came in this wooden box, with no identification of the manufactor whatsoever.
What struck me at first sight was the pieces' ellegant thin "waist", specially the pawn's. Also, despite not being detailly carved, the knights aren't crude either.
Two fun facts about this set:
1) it came with three black knights (!), one of which is visibly smaller than the other two.
2) it came with a weird little piece (only the white one) that I had never seen before. I wonder if its purpose is to be placed on top of a rook and "transform" it into a queen, in case of a pawn promotion, at a time when makers would't think of adding an extra queen to the set... any ideas?
