Hello!

I have this silver filigree cigarette case, but I don't recognize the mark. Maybe one of you knows it. Thank you!

Hi, although you probably already know. For the record I believe it to be Portuguese, domestic silver hallmark used 1938-1984, eagle head, assayed by touchstone for small silver 833/000. The frame shape suggests assay office of Porto. The Portuguese maker's mark unknown to me.
