Hi Alex
your sword is "Persian" it's a "Shamsheer"
the hilt is in "Baddawi" style
the shape of the blade, classifed your sword as "Qara Toban" (a variety of Persian Johar)
seems be 18th Century
the pic identify the blacksmith, the famous "Assad Allah", and a mention about "Abbas Shah"
the long mention on the blade, is a poem written in old Arabic,
unfortunatly my translator don't have the necessary knowledge to offer a translation of it
all the best
