Hi, I feel you all have brought forth some very good reasoning. I found this today
http://www.oriental-arms.com/item.php?id=5017 said to be Mid to Late 19thC Omani. Please note the sheath is basically the same.
I was starting to think I'd seen the same deceitful wood in some Moroccan Koummya's. The pins have indeed been flatted a bit. So, is the age range about right? Thank you all again your incite is appreciated. Steve
Correction 19th C.
