Easy things first, since I have a couple of exams and should not let myself get distracted alot
.
on the original to the right of the date it reads Faqeer Hussain, which I am going to guess is the name of the engraver. Very nicely engraved, also it bears the mark or Toopkhaanah or artillery. I had not seen this type of saber before, during and after living in Afghanistan, so it would mean very few were made or were made for high ranking officials.
I'll do some detailed work maybe tomorrow.
