It was difficult, but I found a reference. Way down on page 102, under "Musical Instruments" it says, "José Mendes Leite, Rua 15 de Novembro, 18." You'll also note that the top of every other page it says "Para." That's a state in northern Brazil.

I do wonder if the manufacturer is Manuel José Mendes Leite. That might make this an interesting historical find.
