Hi.are you sure this is Persian,even from Iran at all? It has a crescent (it must be),same form of which I have seen many times on Indo-Persian shields(especially hide ones). Persians don't use crescent as far as I know. North and South Azerbaijan(Northern Iran) use it but as a Turkish national symbol so it is not expected to be used on a persian revival work,not?But the main point is not necessarily the existence of an supposed crescent,and not who use that symbol and who doesn't. The shield must be Indian or Indo-Persian in origin.Earliest the end of 19th c. or early 20th made for ordinary private guards of somewhere or even for tourists, -if not- much newer, first of all considering the low quality and fastest method of chiselling ,and as the material is brass instead of iron,which is harder to work,but which looks heavier,more respected and real. Plus the figured guy's style looks more Indian than Persian with arm bands or tattoes,naked,big earrings and several necklaces going down till his belly.
