A bronze 17th Century Pilgrims Flask???

Only a similar item found..a "pilgrim flask" that is either 17th or 18th century deccan, indian, persian, or islamic.  It has beautiful engravings including a lotus flower on both sides of the crescent shaped bowl.  There is a symbol or writing in the petal in the center that I have not been able to identify.  Petina fills the engravings as well as a few other spots.  I cannot and have not found another item quite like this one; however, the diamond shaped foot and the notch in the spout seem to be consistent with photos of authenticated pilgrim flasks that are similar.

Please help me determine the true origin, its use, its age, and value... In general, I'd like to know anything I can about it....your imput is valued.
