Omani not Flask Origins

[kahnjar1]

Yes I thought it looked too well made to be tourist, but thought I would ask anyway. If you could establish approx age it might help, but Arabia has been on the "trade routes" for centuries so any neighbouring country that used cast brass in weapons construction could be the place of origin. I would have thought that somewhere close would be more likely as most eastern/islamic countries had specific styles of flasks.
Good luck.
