This looks Indian, not middle eastern. Antique isn't enough to make it valuable as these are a dime a dozen in India, where metal work is very cheap. Value would come from a culturally significant crafter. You'd need to know who made it.

My guess....This sort of brass-work is very commonly churned out by all sorts of Middle-Eastern artisans for the tourist trade. The "engraving" appears to be rather crudely done.
"Antique" is a relative term....The Turks and other folks in the region have been selling this sort of thing for a long time... So It could easily be anywhere from 50-100 years old. But I doubt it's of any great value.
