Atypical Jambiya?

[rockelk]

Atypical Jambiya? I now have a knife I found unusual. It is definitely Middle Eastern by the engravings, but with a slight European style. The sheath is sterling but with no proof markings. It was so tarnished, at first, I thought it was simply brass. It has a pin going thru the tang to reinforce the grip and the tip of the sheath has been repaired and reinforced. The guard / bolster design I find unusual. Unlike most jambiyas the blade is straight and feels substantial. My first (amateur) guess is Moroccan. Any opinions as to its origin, classification and age are sincerely appreciated.
