I had been negotiating for this off-and-on for the last two months. Finally, all the stars aligned, and it has come into my possession.
A textbook example of the form… Hilt is of silver over a horn core. Scabbard is original to the knife, and is of silver (top) and brass (below), separated by copper wire securing what I presume to be the original belt. The blade has a medial ridge as shown and measures +/- 44 cm. The jambiya measures about 58 cm overall (about a half cm more including the scabbard).
I estimate it to be late 19th-early 20th, maybe leaning towards the former?

Good, honest wear to the scabbard. I'm pretty stoked on it, and it already has a place on the wall with our Indo Persian and Islamic antiques…
Anyway, all thoughts and comments welcome.
