POWDER FLASKS---A QUESTION OF ORIGIN

[kahnjar1]

Thanks Gentlemen for the comments above.
So it would appear that the first one shown in my pics is Persian (Iran) origin.
Some discussion still seems to be needed for the other two though. We have "definitely Afghani" and "Arabian" as origins for these. Maybe a common style of making existed in both areas?
The comment from David regarding the use of the cap as a powder measure seems well founded, and thank you for that David.
As to the use of plug type stoppers as opposed to cap type, my only comment here would be that often the neck opening is not "square" with the actual neck, and therefore an internal plug would not necessarily fit properly.
Rick....I have some small tourquoises.
