rod222,
my English is not very good so I may have used the word "guess" the wrong way. I meant suggestion!
Could you share your source for name database?
Foreign postmarks on Brazilian stamps are usually accidental. That is, rare to happen. Therefore, I believe that this may be one of the few that exist from this locality. I myself had never seen another like this ...
I collect these kind of stamps, and they're pretty hard to find. From Italy I only have three more ... Two from Milan (Milano) and one with the inscription "Abbonato"



My best regards,
Claudio
