Help Identify Persian? Hallmark

Swedish import marks, and then.............Persian?

[AG2012]

Hi,
Yes,it is Persia (Iran) because of characteristic numeral 4 in Farsi (Iranian) alfabeth, different from Arabaic.
Flower shaped mark (upside down) is silver standard 84.
It has been discussed as possible old Russian 84 zolotnik standard, but more likely it is simply 840 fineness.
