Great find! One of the fun things about indo-persian weaponry is the creativity of the designers. I think I became hooked on ethnographic weapons the first time I looked through a copy of 'Stones Glossary of Arms and Armor' and wondered, 'how the heck did they use THAT?
The blade is in such nice overall shape I'd be afraid to touch it, and at the same time I'd like to see a clearer pattern in the wootz. Nice blade!
